Answer:
Present Value= $18,181.82
Explanation:
Giving the following information:
Savings= $2,000
The machine will then begin to wear out so that the savings decline at a rate of 4 % per year forever.
Interest rate= 7%
To determine the present value of the savings, we need to use the perpetual annuity formula with the decline rate.
PV= Cf/ (i + g)
Cf= cash flow
PV= 2,000/ (0.07 + 0.04)
PV= $18,181.82
