Question

Toner cartridges for the laser printer in your office cost $90 each, including tax. You receive an $8 refund for each empty cartridge sent back for recycling. Your office uses and recycles 14 cartridges per year. What is your annual toner expense after refunds?

Figure out the cost for 1 cartridge
Cost =       90
Refund =     8 Subtract
Net cost = 82
