Answer:
NPV = $20,000
IRR = 11.25%
Explanation:
first we need to determine the present value of the cash flows using the growing perpetuity formula:
PV = cash flow / (discount rate - growth rate) = $5,000 / (10% - 5%) = $5,000 / 5% = $100,000
The NPV = PV of cash flows - investment = $100,000 - $80,000 = $20,000
to determine the IRR we must find the discount rate that makes NPV = 0
$5,000 / (r - 5%) = $80,000
$5,000 = $80,000 (r - 5%)
$5,000 = $80,000r - $4,000
$5,000 + $4,000 = $80,000r
$9,000 = $80,000 r
r = $9,000 / $80,000 = 0.1125 or 11.25%
