Answer:

Present Value= $14,285.71

Explanation:

Giving the following information:

You are thinking of building a new machine that will save you $1,000 in the first year.

The machine will then begin to wear out so that the savings decline at a rate of 2 % per year forever.

Interest rate= 5%

We need to use the formula of a perpetual annuity. Because of the wear out, we need to sum it to the interest rate the 2%

PV= Cf/(i-wear put)

PV= 1,000 / (0.05 + 0.02)= $14,285.71
