Answer:
See below.
Explanation:
We calculate payback period as,
Payback = initial outlay / savings
Payback = 300,000/ 62500 = 4.8 years
The project has payback of well below 7 years and as such the project is acceptable.
We calculate profits to compute rate of return.
Profit / year = cash flow - depreciation for the year
Depreciation / year = 300,000/15 = $20,000
Profit = 62,500 - 20,000 = $42,500
Rate of return = profit / investment
RoR = 42,500 / 300,000 = 14.16%
Since the RoR is greater than required 10%, the project is acceptable.
Hope that helps.
