Can someone helps with parts 1. and 2. of this question?

The variable operating cost consists of gasoline, oil, tires, maintenance, and repairs. Kristen estimates that, at her current rate of usage, the car will have zero resale value in five years, so the annual straight-line depreciation is $5,450. The car is kept in a garage for a monthly fee. Required: 1. Kristen drove the car 21,000 miles last year. Compute the average cost per mile of owning and operating the car. (Round your answers to 2 decimal places.) 2. Kristen is unsure about whether she should use her own car or rent a car to go on an extended cross-country trip for two weeks during spring break.
