Answer:
12.5%
Explanation:
Computation for the accounting rate of return for the investment
Using this formula
Accounting rate of return=After-tax net income/[(Machine costs+Salvage value)/2]
Let plug in the formula
Accounting rate of return = $12,500/[($180,000 + $20,000)/2]
Accounting rate of return=$12,500/$100,000
Accounting rate of return=0.125*100
Accounting rate of return= 12.5%
Therefore the Accounting rate of return for the investment will be 12.5%
