Answer:
NPV = $13,676.33
Step-by-step explanation:
First, find the present value of the cash inflows. You can solve this question using a Financial calculator;
14,000 per year is a recurring cashflow hence the PMT
PMT = 14,000
I/Y = 10%
N= 9
FV =0
then CPT PV = 80,626.33
NPV = -Initial investment + PV of future cash inflows
NPV = -66,950 + 80,626.33
NPV = $13,676.33
"NPV" button, then , then "CPT".
The answer to the NPV = $13,676.33
