In recent years, Sandhill Corporation has purchased three machines. Because of frequent employee turnover in the accounting

department, a different accountant was in charge of selecting the depreciation method for each machine, and various methods have

been used. Information concerning the machines is summarized in the table below.

For the diminishing$-$balance method, Sandhill Corporation uses double the straight$-$line rate. For the units$-$of$-$production method, total

machine hours are expected to be $21,680.$ Actual hours of use in the first $3$ years were: $2026,420$; $2027,4,110$; and $2028,5,390.$

Prepare separate depreciation schedules for each machine. Prepare the schedule for all years, information permitting. $($Round
