Answer: -$20,529.60
Explanation:
Net Present value of Y = Present Value of Inflows - Present value of Outflows
Present Value of Y inflows
$32,000 inflows for 5 years. This is therefore an annuity
Present value of annuity = Annuity * Present value interest factor, 9%, 5 years
= 32,000 * 3.8897
= $124,470.40
Net Present Value = 124,470.40 - 145,000
= -$20,529.60
