Answer:
Payback is 6.5 years
simple rate of return is 6.50%
Step-by-step explanation:
The payback period for the investment is the number of years it would take the initial capital outlay of $537,600 to recoup itself,which is given by the formula below:
payback period=initial investment/annual incremental savings
initial investment is $537,600
annual incremental savings is $82,708
payback period=$537,600/$82,708= 6.5 years
Simple rate of return =annual savings-depreciation/initial investment
depreciation=($537,600-$107,520)/9=$47,786.67
simple rate of return=($82,708-$47,786.67)/$537,600=6.50%
