In recent years, Splish Transportation purchased three used buses. Because of frequent turnover in the

accounting department, a different accountant selected the depreciation method for each bus, and various

methods were selected. Information concerning the buses is summarized below.

For the declining$-$balance method, the company uses the double$-$declining rate. For the units$-$of$-$activity

method, total miles are expected to be $125,000.$ Actual miles of use in the first $3$ years were: $2019,27,000$;

$2020,35,000$; and $2021,33,000.$
