Answer: $18,000
Step-by-step explanation:
From the question, we are told that Carmel Corporation is considering buying a machine that cost $36,000 with a 6-year useful life and no salvage value and the straight-line depreciation was used on the assumption that the annual cash inflow from the machine will be received uniformly throughout each year.
Accounting rate of return will be the average profit divided by the average investment
The average investment is made of up of the cost of the asset, its salvage value and working capital. Average investment will be the machines and cost divided by 2.
= $36000/2
= $18000.
The average investment is $18,000
