Answer:
$7,190.40
Step-by-step explanation:
The computation of the net present value for the investment A is shown below:
= Present value after considering the discount factor - initial investment
where
 Present value after considering the discount factor is 
= Annual year cash inflows × PVIFA factor for 15% at 3 years 
= $9,500 × 2.2832
= $21,690.40
Refer to the PVIFA table 
And, the initial investment is $14,500
So, the net present value is 
= $21,690.40 - $14,500
= $7,190.40
