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
