Answer: $1,343
Explanation:
Net Present Value = Present value of Cash inflows - Present value of Cash outflows
Cash inflows are constant and so are an annuity.
Present value of Cash inflows = Annuity * Present value interest factor of annuity, 4 years, 10%
= 7,900 * 3.170
= $25,043
Net Present Value = 25,043 - 23,700
= $1,343
