Answer:
dweller accept the this project as NPV value is positive
Step-by-step explanation:
Net present value (NPV) of the project is the total sum of the current value of all the outflows & inflows:
Accept if NPV is positive.
CF = cash flows
r = discount rate = 12%
NPV = - CF_0 + CF_1 / (1 + r) + CF_2 / (1 + r)^2 + CF_3/ ( 1+ r)^3 + CF_4/ (1+r)^4
CF_0 = $80000
CF_1 = $40000
CF_2 = $30000
CF_3 = $30000
discount rate r = 12%
NPV = - 80000 + 40000 / ( 1+ 0.12) + 40000 / ( 1+ 0.12)^2 + 30000/ (1 + 0.12) ^ 3 + 30000 / ( 1+ 0.12)^4
NPV = - 80000 + 35714.29 + 31887.76 + 21353.41 + 19065.54
NPV = $28020.99
therefore dweller accept the this project as NPV value is positive
