The placement of a new surface would reduce the annual maintenance cost to $500 per year for the first 3 years and to $1000 per year for the next 7 years. After 10 years the annual maintenance would again be $2500.
We need to find the net present value. The maximum initial investment will be the amount that makes the NPV cero.
NPV=∑[Cf/(1+i)^n]
Cf= cash flow
<u>For example:</u>
Year 1= 500/1.05= 476.19
Year 3= 500/1.05^3= 431.92
Year 5= 1,000/1.05^5= 783.53
NPV= 6,360.111
The maximum investment is $6,360.111
