Hideki is draining a 45-gallon aquarium at a rate of 15 gallons per minute. what is the initial value of the linear function that represents this situation?

Hideki is draining a 45-gallon aquarium at a rate of 15 gallons per minute. Let's solve for the initial value of the linear function that represents thissituation.
=> 45 gallon aquarium at rate of 15 gallons per minute.
=> 45 gallon / 15 gallon = 3 minutes.
