Answer:
$7,536
Explanation:
As we know Net Present value is calculated by discounting each years cash flows using using the required rate of return.
Saving in labor and other costs per year = $78,000
Initial Investment = $360,000
Numbers of years = 7 years
Required rate of return = 11%
As the saving are constant each year, so we will use the present value of annuity formula to calculate the present value of the cost savings.
Present value of cost saving = $78,000 x ( 1 - ( 1 + 11% )^-7 ) / 11% = $78,000 x 4.712 = $367,536
Net Present Value = Present value of cost saving - initial Investment
Net Present Value = $367,536 + $360,000 = $7,536
