Answer:
NPV -6,422.07908
The investment is not profitable at current cost of capital os 11.6%
Explanation:
Sister Pools 11.6% after tax cost of capital
Contructions 10.3% after tax cost of capital
- 85,000
cash flow 17,000 for next 7 years
We will calculate the present value of a 7-years annuity of 17,000 at 11.6% rate
We use Sister Pools rate because we are asked for this company and there is no indication about a change in the cost of capital condition.
[tex]C \times \frac{1-(1+r)^{-time} }{rate} = PV\\\\\\\\17,000 \frac{1-(1+0.116)^{-7} }{0.116} = PV\\[/tex]
PV = 78,577.92092
Next we subtract the investment cost to get the Net Present Value
78,577.92092 - 85,000 = -6,422.07908
