Contribution margin and contribution margin ratioFor a recent year, McDonald's company-owned restaurants bad the following sales and expenses (in millions): Sales $18,169.3 Food and packaging$6,129.7 Payroll 4,756.0 Occupancy (rent, depreciation, etc.) 4,402.6 General, selling, and administrative expenses 2,487.9   $17,776.2 Income from operations$ 393.1 Assume that the variable costs consist of food and packaging; payroll; and 40% of the general, selling, and administrative expenses. a. What is McDonald’s contribution margin? Round to the nearest tenth of a million (one decimal place). b.  What is McDonald’s contribution margin ratio? Round to one decimal place. c.  How much would income from operations increase if same-store sales increased by $500 million for the coming year, with no change in the contribution margin ratio or fixed costs? Round your answer to the nearest tenth of a million (one decimal place). a. To determine Contribution Margin: It is defined as the difference between the sales and the variable cost. Contribution Margin ratio: It is a ratio that measures the contribution margin generated by the company from the sales to make it avialable for paying the fixed cost and generate a profit. It is expressed as percentage of margin available from each dollar sales to pay fixed expenses and to provide profit. It is also called as profit-volume ratio. The formula to calculate the contribution margin ratio is as follows: ContributionMarginRatio =ContributionMarginSales×100 To determine: contribution margin for M Company. Explanation Determine the contribution margin for M Company. Sales =$18,169.3 million

Variable cost =11,880.9 million (1)

ContributionMargin=SalesVariablecost=$18,169.3$11,880.9=\$6,288.4million

Working notes:

Determine the total variable cost.

Totalvariablecost=(Food
