A water contained 35 gallons of water at first. Due to a leak at the bottom of the tank, the amount of water in the tank decreased to 32 gallons after 1 hour. After another hour, the amount of water in the tank was 26 gallons. Find the percent decrease in the amount of water from 35 gallons to 32 gallons. Round your answer to the 1 decimal place.

The percent decrease wouldn't have anything to do with the rates of the flow.
The formula is:
x% = (new value - old value) * 100%
The new value would be the 32 here. The old value would be 35 (starts at 35, old; ends at 32). Plugging the numbers in:
x% = (32 - 35) *100%
x% = -8.6%
The negative sign only means it was a decrease of 8.6%.
Good luck, user3407588. I hope this helps.
