A college student has set aside $240 for the rest of the school year to use the coin-operated laundry facility in his dormitory. Each time he uses the machines, it costs $7.50. Choose the equation that represents the amount remaining in his fund, f, after he has done laundry x times. Find the amount remaining in the fund after 12 trips to the laundry facility.

• f = 240 - 7.50x ; $90

• f = 240 - 7.50x ; $150

• f = 7.50 - 240x ; $90

• f = 7.50 - 240x ; $150
