Answer:
$40
$32
Explanation:
It says that both your friend's monthly allowance and your monthly allowance together is $72. To find out how much one box is worth, we need to divide $72 by 9 because there are 9 boxes. 72 ÷ 9 = 8.
We know that each box is equal to $8.00, so to find out how much your monthly allowance is, we multiply 8 by 5 because you have five squares. 8 x 5 = 40.
To find out how much money your friend's monthly allowance is, we multiply 8 by 4 because your friend has four squares. 8 x 4 = 32.
We can check our work by adding 40 and 32 together. 40 + 32 = 72. Which means that it is correct. :)
I hope that this helps!
