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 $1,776,000 560,000 February 2,700,000 1,000,000 March 1,650,000 500,000 1,860,000 600,000 April May 1,440,000 400,000 460,000 June 1,566,000 Determine the variable cost per gross-ton mile and the total fixed cost. Variable cost (If required, round to two decimal places.) per gross-ton mile Total fixed cost Break-Even Sales Currently, the unit selling price of a product is $1,500, the unit variable cost is $1,200, and the total fixed costs are $4,500,000. A proposal is being evaluated to increase the unit selling price to $1,600. a. Compute the current break-even sales (units). units b. Compute the anticipated break-even sales (units), assuming that the unit selling price is increased and all costs remain constant. units
