3. Beginning food inventory is \$9,800, purchases are \$6,200, and ending inventory is \$10,100.
Food sales are \$19,600. What is the unadjusted food cost percentage?
4. Sales tax collected from guests is recorded as:

\$33,600. What is prime cost in dollars and percent?
6. Which statement about EBITDA is correct?
A. it is the same as cash flow
B. it excludes depreciation, which is a real cash cost
C. it excludes the principal portion of debt service, which is a real cash cost
D. it is computed after interest expense
7. An operator says "my food cost is 28% — I divide my invoices by my food sales." What is the
single most likely reason that number is wrong, and in which direction does buying heavy at the end
of a period push it?
8. Bellwether's plan carries labor at \$500,000, of which \$415,000 is wages and salaries. What
percentage does the burden — payroll taxes, workers' comp, and benefits — add on top of every wage
dollar?

A. exactly one calendar month
B. four weeks, 28 days, and four of each weekday
C. either four or five weeks depending on the quarter
D. 30 days
10. Which is variable but non-controllable?
A. base rent
B. credit-card processing fees
C. hourly labor hours
D. salaried management wages
11. Bellwether's base grid produces \$27,130 a week and the plan's top line is \$1,550,000. What
is the annual revenue bridge, and what percentage of the top line is it?
12. A restaurant transfers \$185 of citrus and herbs a week from the kitchen to the bar and never
logs it. What happens to reported food cost and reported pour cost?
13. Controllable income is the line that stops before:
A. cost of sales
B. labor
C. occupancy, insurance policies, contracted technology, and G&A
D. depreciation only
14. A restaurant's annual debt service is \$69,500, of which \$39,700 is interest. How much of
the \$69,500 appears as an expense on the profit-and-loss statement, and where does the remainder go?
15. Why must the inventory count, the sales figures, and the payroll export all cover the same
seven-day window?
16. A weekly flash report should be produced:
A. when the bookkeeper closes the month
B. within one business day of the operating week's close
C. quarterly, to match the tax calendar
D. only when a number looks wrong
17. Comps of \$486 on net sales of \$30,400 with prime cost of \$18,953. What is prime cost
percent as reported, and what would it have been with no comps? (Round to one decimal.)
18. True or false: recording comps as marketing expense instead of contra-revenue changes
operating profit. Explain your answer.
19. Bellwether's first quarter runs at 66.6% prime cost and the year must land at 60.0%. What
must weeks 14 through 52 average, and why is a flat 60% target on the flash report actively harmful?
20. A staffing plan says 31 heads, a labor model says 24 scheduled positions, and the schedule
carries 453.5 hourly hours a week. Which of these three is the number you multiply by a wage rate,
and what do the other two answer?
21. Under cash accounting, a month in which you stretch your vendors:
A. looks worse than it was
B. looks better than it was, and the following month looks worse
C. is unaffected
D. cannot be computed
22. Bellwether's occupancy is 6.1% of sales. Explain, in one sentence, why that single fact is
what allows the restaurant to survive a 66.3% prime cost when Chapter 1 called that band
"distressed."
23. Property insurance sits in occupancy and general liability sits in other operating. If you
moved \$29,300 of general liability into occupancy on \$1,550,000 of revenue, what would happen to
the reported occupancy and other-operating percentages?
24. Which of these is not a reason to run a foodservice-specific chart of accounts?
A. so pour cost can be computed by beverage category
B. so card processing can be seen separately from other bank fees
C. so the P&L falls out of the accounts in the right order
D. so operating profit is higher
25. A restaurant's March has an extra Friday, Saturday, and Sunday compared with February. Is a
March-over-February revenue comparison meaningful? What calendar fixes this and how?
26. State the difference between a dine time and a table cycle, and say which of the two
is always the larger number.
Answer key
**1.** **B.** Cost of goods sold plus total labor, as a percentage of total sales. Labor means
all-in: wages, salaries, overtime, payroll taxes, workers' comp, and benefits, for everyone.
**2.** **C.** A void. Nothing was consumed and nothing was sold, so it touches neither revenue nor
cost of sales. It exists only in the POS audit trail, which is why a fraudulent void is invisible on
every financial statement — and why Chapter 34 watches voids by employee and by hour.
**3.** Usage = \$9,800 + \$6,200 − \$10,100 = **\$5,900**. \$5,900 ÷ \$19,600 = **30.1%**. Note that
the purchases-over-sales shortcut would have reported \$6,200 ÷ \$19,600 = 31.6% — the walk-in grew
\$300 and the shortcut charged you for it.
**4.** **B.** A liability, in account 2200. It is collected as an agent for a taxing authority and it
was never your money, even though it sits in your operating account looking exactly like cash.
**5.** Prime cost = \$9,140 + \$11,860 = **\$21,000**, and \$21,000 ÷ \$33,600 = **62.5%**.
**6.** **C.** EBITDA excludes the principal portion of debt service, which really does leave the bank
account. Excluding depreciation is correct — depreciation is genuinely non-cash — which makes B
false, and EBITDA is computed *before* interest, which makes D false.
**7.** They have not counted ending inventory, so they do not have the numerator — they have
purchases, not usage. Buying heavy at the end of a period pushes the reported number **up** (it looks
worse), and running the walk-in down pushes it **down** (it looks better). Neither movement has
anything to do with what the kitchen actually used.
**8.** \$500,000 − \$415,000 = \$85,000 of burden on \$415,000 of wages = **20.5%**. Every additional
hour costs the rate times 1.205.
**9.** **B.** Four weeks, 28 days, four of each weekday — 364 days a year, which is why a 53rd week
arrives every five or six years and must be flagged in every comparison.
**10.** **B.** Card processing rises and falls with sales dollar for dollar (variable) and the rate is
contractual, so a manager cannot change it this week (non-controllable). Rent is fixed and
non-controllable; hourly hours are variable and controllable; salaried wages are fixed and
controllable.
**11.** \$27,130 × 52 = \$1,410,760. \$1,550,000 − \$1,410,760 = **\$139,240**, which is
\$139,240 ÷ \$1,550,000 = **9.0%** of the top line.
**12.** Food cost is **overstated** and pour cost is **understated**. At \$185 a week that is \$9,620
a year — about 0.9 points of food cost on \$1,116,000 of food sales and about 2.2 points of pour cost
on \$434,000 of beverage sales. The chef spends a month chasing a problem that is sitting in a
cocktail.
**13.** **C.** Controllable income stops before occupancy, insurance policies, contracted technology,
and general and administrative expense — everything a manager did not negotiate and cannot change.
Cost of sales and labor are *inside* controllable income, not below it.
**14.** Only the **\$39,700 of interest** is an expense on the P&L. The remaining **\$29,800 of
principal** reduces the loan balance on the balance sheet and never appears on the income statement,
even though it is a real cash outflow.
**15.** Because prime cost is a ratio of two sums over a period, and if the numerator covers a
different seven days than the denominator, the ratio describes nothing. Payroll systems commonly
default to a Sunday-to-Saturday week; if your operating week is Tuesday-to-Monday, your labor
percentage will oscillate for reasons that have nothing to do with the schedule.
**16.** **B.** Within one business day. A flash report is deliberately approximate — 95% accurate on
Monday beats 100% accurate on the 22nd, because on Monday you can still do something about it.
**17.** As reported: \$18,953 ÷ \$30,400 = **62.3%**. With no comps, sales would have been \$30,886
and prime cost would be \$18,953 ÷ \$30,886 = **61.4%**. The numerator never changed; \$486 of
generosity moved prime cost 0.98 points.
**18.** **False.** Operating profit is identical either way — the money is gone in both treatments.
What changes is the *denominator*: routing comps to marketing overstates revenue, which artificially
improves every cost percentage on the statement and puts something in the marketing line that is not
marketing. In a business managed by percentages, corrupting the denominator is the whole crime.
**19.** Weeks 14–52 must average **58.0%**. Q1 revenue works out to \$363,720 and the remaining 39
weeks to \$1,186,280; 0.666 × \$363,720 + 0.580 × \$1,186,280 = \$930,280, which is 60.0% of
\$1,550,000. A flat 60% target makes the operator think they are failing for thirteen weeks when they
are on plan, and think they are winning in the third quarter when they are two points behind where
the year requires them to be.
**20.** **453.5 hourly hours** is the number you multiply by a wage rate. **31 heads** answers "how
many people must I recruit, onboard, certify, and replace against 75% turnover." **24 scheduled
positions** answers "how many slots must the weekly schedule fill." All three are correct answers to
different questions and none substitutes for another.
**21.** **B.** Cash accounting records the expense when the money leaves, so deferring payment defers
the expense — the month looks profitable and the following month absorbs both. You have learned
nothing true about either month.
**22.** Because Chapter 1's prime-cost bands assume a typical full-service occupancy of 6–10%, and at
the low end of that range there is roughly four points of sales — about \$60,000 a year at
Bellwether's volume — that a higher-rent operator has already spent before the prime-cost
conversation starts.
**23.** Occupancy would rise from **6.1% to 8.0%** (\$95,200 + \$29,300 = \$124,500) and other
operating would fall from **14.0% to 12.1%** (\$217,000 − \$29,300 = \$187,700). Same restaurant,
same money — which is exactly why you cannot benchmark against a percentage without knowing how the
accounts were defined.
**24.** **D.** A chart of accounts cannot change operating profit. It changes what you can *see*, and
therefore what you can manage and what you can honestly compare against anybody else.
**25.** No, it is meaningless. An extra Friday, Saturday, and Sunday is real revenue that has nothing
to do with how the restaurant was run, and every fixed cost's percentage improves at the same time. A
**13-period calendar** fixes it by making every period exactly four weeks with exactly four of each
weekday, so period-over-period comparisons hold the calendar constant.
**26.** A **dine time** runs seated-to-paid and belongs to the guest. A **table cycle** runs
seated-to-seated and belongs to the table, so it includes the bus-and-reset. **The cycle is always
the larger of the two.** Do not subtract one from the other and call the difference "reset time" —
report the cycle when building a reservation grid and the dine time when measuring a service.
