Question

Patti's Pet Palace has an 85 gallon fish tank. When it needs to be cleaned, it can be drained at a rate of 3 gallons per minute. Assuming the tank was full, and x represents the number of minutes the tank has been draining, which of the following functions represents the amount of water in the tank after x minutes?

f(x) = 3x + 85
f(x) = 85 - 3x
f(x) = 85x - 3
f(x) = 3x - 85
