Joyce Murphy runs a courier service in downtown Seattle. She charges clients $0.50 per mile driven. Joyce has determined that if she drives 3,300 miles in a month, her total operating cost is $875. If she drives 4,400 miles in a month, her total operating cost is $1,095. Required: 1. Using the high-low method, determine Joyce's variable and fixed operating cost components. (Round your cost per unit answer to 2 decimal places.) 2. Complete the contribution margin income statement for Joyce's service assuming she ove 2,400 miles last month. (Assume this falls within the relevant range of operations)
