I was able to make it through most of this but got my first attempt partially right, can you explain to me how you come up with the answers for the rest of this problem? This is a chapter on Plant Assets, Natural Resources, and Intangible Assets. Thanks!

Exercise 95 (Part Level Submission) Yello Bus Lines uses the unitsofactivity method in depreciating its buses. One bus was purchased on January 1, 2017, at a cost of $224,158. Over its 4year useful life, the bus is expected to be driven 153,800 miles. Salvage value is expected to be $7,300. (a) Your answer is correct. Compute the depreciable cost per unit. (Round answer to 2 decimal places, e.g. 0.50.) Depreciation cost per unit SHOW SOLUTION 1.41 $ per mile SHOW ANSWER LINK TO TEXT Attempts: 1 of 3 used (b) Your answer is partially correct. Try again. Prepare a depreciation schedule assuming actual mileage was: 2017, 25,800 2018, 46,000 2019, 39,000 and 2020, 43,000. (Round cost per unit to 2 decimal places, e.g. 15.25 and all other answers to 0 decimal places, e.g. 5,275.)
