Answer:
No, I would not accept the project.
Step-by-step explanation:
The initial investment will be equipment cost of $200,000 plus working $15,000 totaling to $215,000.
The cash flow after tax will be $26,000 {$40,000 x (1 - 35% tax rate)}
The salvage value of the equipment is $70,000 plus working capital of $15,000 totaling to a value of $85,000.
Following formula will be used to calculate present value of annuity payment of $26,000 for four years and present value of $85,000:

PV = Present Value
PMT = Annuity Payment
r = Interest Rate
FV = Future Value
n = Number of periods
Calculation
Data:
r = 5%
n = 4
PMT = $26,000
FV = $85,000

The net present value of the project is $215,000 - $162,124.42 = $-52,875.58
The project is not economically valuable.
