Answer:
(b) For each minute the washing machine runs, it uses 3/5 of a gallon of water.
Explanation:
You want to know the meaning of g = 3/5m when g is gallons used by a washing machine in a period of m minutes.
Interpretation
The problem statement tells you m represent minutes and g represents gallons, so m=1 would tell you the gallons used in 1 minute:
g = 3/5(1) = 3/5
The machine uses 3/5 gallon of water for each minute it runs.
