Answer: $126,613
Explanation:
Net Present value of Project A is:
= Present value of $50,000 annuity + Present value of residual value - Initial investment
Present value of $50,000 annuity:
= 50,000 * ( 1 - ( 1 + rate)^-number of periods) / rate
= 50,000 * ( 1 - ( 1 + 12%) ⁻⁸) / 12%
= $248,382
Present value of residual value:
= 8,000 / ( 1 + 12%)⁸
= $3,231
Net present value
= 248,382 + 3,231 - 125,000
= $126,613
