Answer:
a, The depreciable cost when using the straight line method is;
= Cost of asset - Residual value
= 70,700 - 4,200
= $66,500
b. As the rate is uniform over the life of the asset, the rate is 100% divided by the life of the asset.
= 100%/5
= 20%
c. Annual depreciation will therefore be;
= Depreciation rate * depreciable cost
= 20% * 66,500
= $13,300
