Charlie's goal is to use less than 50 gallons of water per day. His water bill for the month showed that he used 1524 gallons of water in 30 days....

Charlie's goal of use of water per day = 50 gallons

Water consumption for 30 days = `50xx30 ` = 1500 gallons

Charlies water bill indication of usage = 1524 gallons

1500 < 1524

Expected usage < Actual usage

So we can see that charlie's usage of water is little bit higher than her expected usage.

Charlie has not met her goal.
