Final answer:
The accounting rate of return (ARR) for Proposal X is calculated by subtracting the average annual depreciation from the estimated annual net cash inflows and dividing by the initial investment. The ARR for Proposal X is 7.57%.
Step-by-step explanation:
The accounting rate of return (ARR) for Proposal X can be calculated using the formula:
ARR = (Average Annual Profit / Initial Investment) × 100%
To find the average annual profit, we need to subtract the average annual depreciation from the estimated annual net cash inflows:
Average Annual Depreciation = (Investment - Residual Value) / Useful Life
Average Annual Depreciation for Proposal X = ($850,000 - $79,000) / 9 years = $85,667 (rounded to the nearest dollar).
Average Annual Profit = Estimated Annual Net Cash Inflows - Average Annual Depreciation
Average Annual Profit for Proposal X = $150,000 - $85,667 = $64,333 (rounded to the nearest dollar).
Now we can calculate the ARR for Proposal X:
ARR for Proposal X = ($64,333 / $850,000) × 100% = 7.57% (rounded to the nearest hundredth of a percent).
The accounting rate of return for Proposal X is 7.57%.
