Answer:

A

Explanation:

Net present value is the present value of after-tax cash flows from an investment less the amount invested.

NPV can be calculated using a financial calculator  

Cash flow in year 0 = $-165,000

Cash flow in year 1 - 6  = $45,000

I = 12%

NPV = $20,013.33

the project should be approved because NPV is positive

To find the NPV using a financial calculator:

1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.

2. after inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.
