The options provided are incorrect. The correct answer is given below.
Answer:
Residual value = $28000
Step-by-step explanation:
The straight line method of charging depreciation is a method that charges a constant depreciation expense throughout the useful life of the asset. The formula to calculate the depreciation expense under the straight line method is as follows,
Depreciation expense = (Cost - Residual value) / Estimated useful life of the asset
Plugging in the values for depreciation expense, cost and estimated useful life, we can calculate the residual value to be,
5000 = (68000 - Residual value) / 8
5000 * 8 = 68000 - Residual value
40000 + Residual value = 68000
Residual value = 68000 - 40000
Residual value = $28000
