High-Low Method for a Service Company 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. Transportation Costs Gross-Ton Miles January $954,500 254,000 February 1,064,200 284,000 March 752,100 184,000 April 1,020,300 275,000 May 855,700 221,000 June 1,097,100 299,000 Determine the variable cost per gross-ton mile and the fixed cost. Variable cost (Round to two decimal places.) per gross-ton mile Total fixed cost Contribution Margin and Contribution Margin Ratio For a recent year, Wicker Company-owned restaurants had the following sales and expenses (in millions): Sales $20,300 Food and packaging $6,489 Payroll 5,100 Occupancy (rent, depreciation, etc.) 5,101 General, selling, and administrative expenses 3,000 $19,690 Income from operations $610 Assume that the variable costs consist of food and packaging, payroll, and 40% of the general, selling, and administrative expenses. a. What is Wicker Company's contribution margin? Round to the nearest million. (Give answer in millions of dollars.) $ million b. What is Wicker Company's contribution margin ratio? Round to one decimal place. % c. How much would income from operations increase if same-store sales increased by $1,200 million for the coming year, with no change in the contribution margin ratio or fixed costs?
