Machine B: The recorded cost of this machine was $$180,000.$ Monty estimates that the useful life od the machine is $4$ years with a $$19,500$ salvage value remaining at the end of that time. Calculate the amount of depreciation expense that Monty should record for Machine B each year of its useful life under the

following assumptions. $($Round depreciation cost per unit to $2$ decimal places, e$.$g$.12\mathrm{.}25.$ Round final answers to $0$ decimal

places, e$.$g$.2,125.)$

$(1)$ Monty uses the straight$-$line method of depreciation.

$(2)$ Monty uses the declining$-$balance method. The rate used is twice the straight$-$line rate.

$(3)$ Monty uses the units$-$of$-$activity method and estimates that the useful life of the machine is $107,000$ units. Actual usage

is as follows: $2022,45,500$ units; $2023,31,500$ units; $2024,17,500$ units; and $2025,12,500$ units.
