Question

At the end of a long drought, the local reservoir was at 35% capacity. After three weeks of steady rain, however, the level rose to 60% capacity. If this increase amounted to 10,000 more gallons in the reservoir, how many gallons does the reservoir hold?

Answer 1

The big key here is finding out what that 10,000 really represents. You are given 60% as the stopping point and 35% as the start, so 60-35=??? That is the % you know and the key to answering this.
