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.) $ X per gross-ton mile Total fixed cost
