A tank containing 35 gallons of water is leaking at a rat 1/4 gallon per minute. Write and expression to determine the number of gallons left in the tank after m minutes

The expression 35 - m is used to determine the number of gallons left in the tank after m minutes. Solution:Given that a tank containing 35 gallons of water is leaking at a rate of gallon per minute. Let "m" represent the number of minutes spent Number of gallons left in the tank = initial amount of water present - leaked amount of water

Number of gallons of water left = 35 gallons - number of minutes spent rate of leakage.

Number of gallons of water left = 35 gallons - m minutes 1 gallons per minute Hence, the required expression is 35 - m
