A merchant is selling wind chimes from a booth at a flea market.

He rents his space for $125 per day.

The profit from each wind chime sold is $12.

His goal is to make $3500 in a five day work week.

Which equation represents how many

chimes he needs to sell in a week to meet his goal?

• 12c – 625 = 3500

• 5(12c) – 125 = 3500

• 5(12c + 125) = 3500

• 5(12c – 125) = 3500
