Answer:
Project X = $6,980.82
Project Y = - $2,478.42
Explanation:
The Present value is the price today of future cash flows and is calculated as follows :
Project X
($21,000) CF 0
$8,000 CF 1
$8,000 CF 2
$8,000 CF 3
$8,000 CF 4
$8,000 CF 5
$8,000 CF 6
I/YR = 18%
Therefore, NPV is $6,980.82
Project Y
($21,000) CF 0
$0 CF 1
$0 CF 2
$0 CF 3
$0 CF 4
$0 CF 5
$50,000 CF 6
I/YR = 18%
Therefore, NPV is - $2,478.42
