Exercise $10-13($Algo$)$ Revising depreciation LO C$2$

Apex Fitness Club uses straight$-$line depreciation for a machine costing $$30,300,$ with an estimated four$-$year life and a $$2,550$ salvage value. At the beginning of the third year, Apex determines that the machine has three more years of remaining useful life, after which it will have an estimated $$2,100$ salvage value.

Compute the machine$$s book value at the end of its second year.

Compute the amount of depreciation for each of the final three years given the revised estimates.
