A Container holds 70,000 ounces of water There is a small leak in the container Every 96 minutes, 1.8 ounces of water leaks out Represent the total change in the amount of water in the container after 6 hours

Suppose that in 6 hours = 360 minutes x ounces of water will leak. Make a proportion:

1.8 / 96 = x / 360 => x = 360*1.8 /96 = 6.75, so the total change in the amount of water is 6.75 ounces. This is very little compared to the total amount.
