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 [tex]\times[/tex] rate of leakage.
Number of gallons of water left = 35 gallons – m minutes [tex]\times[/tex] 1 gallons per minute
[tex]= 35 - m \times 1 = 35 - m[/tex]
Hence, the required expression is 35 – m
Answer:
8.75
Step-by-step explanation
1/4 is a substitute for m so 1/4 x 35 = 8.75
