Joyce murphy runs a courier service in downtown seattle. she charges clients $0.62 per mile driven. joyce has determined that if she drives 2,900 miles in a month, her total operating cost is $950. if she drives 4,000 miles in a month, her total operating cost is $1,192. required: 1. using the high-low method, determine joyce’s variable and fixed operating cost components.

Variable cost per mile = 0.22 per mile

Total fixed cost = $312

Explanation:

If she drives 2,900 miles then,

Total operating cost = $950

If she drives 4,000 miles then,

Total operating cost = $1,192

Using high low method,

variable cost per mile:

= 0.22 per mile

Hence,

Total fixed cost = 1,192 - (4,000 × 0.22)

                          = 1,192 - 880

                          = $312
