Answer:
T = 600 + 25m
Step-by-step explanation:
Initially, there are 600 gallons in the tank.
Then, we add 25 gallons per minute. it means that after m minutes, the tank has 25*m gallons.
So, the algebraic expression is the sum of the initial number of gallons and the number of gallons that we add every minute, then:
T = 600 + 25m
Where T is the number of gallons in the tank
