27 of her money and Cody spent
12 of his money, they each had an equal amount of money left. How much money did they spend altogether?

Gabby |
Cody |
Total |
Before |
7 u |
2x5 = 10 u |
$68 |
Change |
- 2 u |
- 1x5 = - 5 u |
|
After |
5 u |
1x5 = 5 u |
|
The amount that Gabby and Cody each had in the end is the same. Make the amount that each had in the end the same. LCM of 5 and 1 is 5.
Total amount that Gabby and Cody had at first
= 7 u + 10 u
= 17 u
17 u = 68
1 u = 68 ÷ 17 = 4
Total amount that Gabby and Cody spent
= 2 u + 5 u
= 7 u
= 7 x 4
= $28
Answer(s): $28
