Answer:
NPV= 5,493.79
Explanation:
<u>To calculate the net present value (NPV), we need to use the following formula:</u>
NPV= -Io + ∑[Cf/(1+i)^n]
Cf1= 18,708 / 1.09= 17,163.30
Cf2= 21,200 / 1.09^2= 17,843.62
Cf3= 17,800 / 1.09^3= 13,744.87
∑[Cf/(1+i)^n]= $48,751.79
NPV= -43,258 + 48,751.79
NPV= $5,493.79
