An energy-efficient motor may be purchased for $3,000 that will last for 5 years. It will save $800 in year one, and savings will increase by 8% annually, thereafter. It will cost $100 to maintain in year two, and increase by 10% thereafter. Given our company uses 10% as a rate of return, calculate the present worth. How much must the first annual cost increase for the motor to no longer be cost effective?
