A gasoline driven pump and an electric driven pump are being considered for use in a mine for a period of 10years.

Gasoline:
First Cost $15000
Life Years 5
Salvage Value $1000
Annual Operation $4000
Annual Repair $1000
Taxes 3%

Electric:
First Cost $28000
Life Years 10
Salvage Value $2000
Annual Operation $2400
Annual Repair $800
Taxes 3%

If money is worth 10% which should you recommend?

Solve by ROR, AW,and FW method..

I m also bothered by the word "TAXES" ,, where do I apply it? in first cost? annual operation? or annual repair? please help me out.. thank you very much
