Depreciation for Partial Periods

Clifford Delivery Company purchased a new delivery truck for $54,000 on April 1, 2019. The truck is expected to have a service life of 5 years or 180,000 miles and a residual value of $3,000. The truck was driven 10,000 miles in 2019 and 16,000 miles in 2020. Clifford computes depreciation expense to the nearest whole month.
