The number of gallons of water in a tank that already has 300 gallons in it after being filled at 35 gallons per minute for m minutes

300 + 35m

Step-by-step explanation:

We have to convert the given statement into an algebraic expression. The tank already has 300 gallons of water in it and it is being filled at a rate of 35 gallons per minute.

Since, in 1 minute the 35 gallons of water is being added to tank, in "m" minutes 35m gallons of water will be added to the tank.

So, after m minutes the total water in the tank will be:

Water available initially + Water added in m minutes

= 300 + 35m

This expression represents the total amount of water in the tank after m minutes.
