Answer:the number of gallons of water left in the tub after it has drained for x minutes is 300 - 8x
Step-by-step explanation:
A hot tub that holds 300 gallons of water drains at a rate of 8 gallons.
Let x represent the number of minutes for which the hot tub has drained water.
If the hot tub drains 8 gallons of water per minute, it means that in x minutes, the number of gallons of water that the hot tub would have drained is 8x
Therefore, the number of gallons of water left in the tub after it has drained for x minutes would be
300 - 8x
