Three classes at a junior high school raised money to buy new computers. ms. moore’s class raised $249.00. ms. aguilar raised $396.62 more than ms. moore’s class. mr. barry raised $430.43 less than ms. aguilar’s class. what is the total amount of money raised by all three classes?

The final amount is $1109.81

Step-by-step explanation:

In order to find the total amount, start with the know amount, which is Ms. Moore's class. Her class raised $249. Now we can use that to find the amount from Ms. Aguilar's class.

$249 + $396.62 = $645.62

Now we can use the amount from Ms. Aguilar's class to find the amount from Ms. Barry's class

$645.62 - $430.43 = $215.19

Now we can add the three amounts together to find the total amount.

$249 + $645.62 + $215.19 = $1109.81
