Question

Charlies goal is to use less than 50 gallons of water per day. His water bill showed that he used 1524 gallons of water in 30 days. Did Charlie meet his goal?

Answer 1

No he used 50.8 gallons a day 
$\frac{1524}{30} =50.8$

Answer 2

First you divide 1524 by 30 which is 50.8. That means if he used the same amount of water per day, he used 50.8 gallons of water. 50.8 gallons of water is more than 50 gallons of water. So, no he did  reach his goal.
