Linear Equations Multiple Representations

A water tank currently contains 275 gallons of water. The amount of water in the tank will decrease at a constant rate of 15 gallons per week.

Which function can be used to find t, the total number of gallons of water in the tank after w weeks?

• t=15w-275

• t=-15w+275

• t=275w-15

• t=-275w+15
