Boston Railroad decided to use the high-low method and operating data from the past six months to estimate the fixed and variable components of transportation costs. The activity base used by Boston Railroad is a measure of railroad operating activity, termed "gross-ton miles," which is the total number of tons multiplied by the miles moved. Determine the variable cost per gross-ton mile and the total fixed cost. Variable cost (Round to two decimal places.) Total fixed cost $ $ per gross-ton mile Contribution Margin and Contribution Margin Ratio For a recent year, McDonald's Company-owned restaurants had the following sales and expenses (in millions): 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 million. (Give answer in millions of dollars.) $ million b. What is McDonald's contribution margin ratio? % c. How much would income from operations increase if same-store sales increased by $2,000 million for the coming year, with no change in the contribution margin ratio or fixed costs? Round your answer to the closest million. $ million Break-Even Sales Anheuser-Busch InBev Companies, Inc., reported the following operating information for a recent year: In addition, assume that Anheuser-Busch InBev sold 43,000 barrels of beer during the year. Assume that variable costs were 75% of the cost of goods sold and 50% of selling, general, and administration expenses. Assume that the remaining costs are fixed. For the following year, assume that Anheuser-Busch InBev expects pricing, variable costs per barrel, and fixed costs to remain constant, except that new distribution and general office facilities are expected to increase fixed costs by $25,800. a. Compute the break-even number of barrels for the current year. Round to the nearest whole barrel. barrels b. Compute the anticipated break-even number of barrels for the following year. Round to the nearest whole barrel. barrels
