question

Two pumping systems are being considered for use on a project. The gasoline pump will cost

3,500, has a 6 year life year, and a

500 salvage value. Annual operating and repair costs would be

2,000 the first year, and would rise

300 each succeeding year. The electric pumping system costs

12,000, has a life of 6 years and a salvage value of

1,000. Annual operating and maintenance costs would be

1,000 the first year, and would rise

150 each year. If the current interest rate is 10%, compare the equivalent annual costs of the two pumping systems. Assume all maintenance and repair costs are paid at the end of each year.

Original LaTeX notation

Two pumping systems are being considered for use on a project. The gasoline pump will cost $3,500, has a 6 year life year, and a $500 salvage value. Annual operating and repair costs would be $2,000 the first year, and would rise $300 each succeeding year. The electric pumping system costs $12,000, has a life of 6 years and a salvage value of $1,000. Annual operating and maintenance costs would be $1,000 the first year, and would rise $150 each year. If the current interest rate is 10%, compare the equivalent annual costs of the two pumping systems. Assume all maintenance and repair costs are paid at the end of each year.
