Answer:
a) $3077
b) The owner should make this investment because the marginal benefit is greater than the marginal cost
Step-by-step explanation:
Given data :
Total cost = $2000
depreciation rate = 8% per year
expected increase in revenue (CF ) = $400
interest rate = 5%
a) Determine the present value of the stream of revenue due to the upgrades
= CF / ( 1 + r ) ^t where ( 1 + r )^t = 13%
= 400 / 13%
= $3077
b) The owner should make this investment because the marginal benefit is greater than the marginal cost
