Answer:
3.64%
Step-by-step explanation:
Annual depreciation expenses = (Cost of new machine - Salvage value)/Expected useful life = ($33,000 - $8,000) ÷ 5 = $25,000 ÷ 5 = $5,000
Annual net income = (Annual before tax net cash inflow - Annual depreciation expenses) × (1 - Income Tax Rate) = ($7,000 - $5,000) × (1 - 40%) = ($2,000) × (0.60) = $1,200
Since unadjusted rate of return does not take into account the time value of money, it can therefore before computed as follows:
Unadjusted rate of return = Annual net Income ÷ Cost of new machine = $1,200 ÷ $33,000 = 0.0364, or 3.64%
