c. How much would income from operations increase if same-store sales increased by $811 million for the coming year, with no change in the contribution margin ratio or fixed costs? Round your answer to the closest million.


Answer:

a. Sales (in millions)…………………………………………………………………… $16,233
Variable costs (in millions):
Food and packaging……………………………………………………………… $ 5,300
Payroll……………………………………………………………………………… 4,121
General, selling, and administrative expenses (40% × $2,334)…………… 934
Total variable costs…………………………………………………………… $10,355
Contribution margin (in millions)………………………………………………… $ 5,878
b. Contribution Margin Ratio = Sales – Variable Costs
Sales
Contribution Margin Ratio = $5,878 million
$16,233 million
= 36.2%
c. Same-store sales increase (in millions)…………………………………… $811 million
Contribution margin ratio (in millions) [from part (b)]…………………… × 36.2%
Increase in income from operations (in millions)……………………… $294 million
