The sixth grade has collected $116 for a local animal shelter. Their goal is to collect $500.00. They have three weeks left. How much money must they collect each week?

Answer 1

500 = 116 + 3x

3x = 500 - 116

3x = 384

x = 128

Answer 2

If they need $500.00 total and have $116.00 so far, then they need $384.00 more to reach their goal.

To set up an equation now, we can call X the number of money per week. Therefore, 3 times the number of money needed per week equals $384.00, or just 3X = 384. Divide both sides of the equation by 3 to get X=$128.00.
