35 as much money as Victoria. Opal received another $49 from her aunt and Victoria spent $9 on some markers. In the end, Opal and Victoria had an equal amount of money. How much money did the girls have altogether in the end?

Before |
3 u |
5 u |
|
Change |
+ $49 |
- $9 |
|
After |
3 u + $49 |
5 u - $9 |
8 u + $40 |
Amount of money Opal and Victoria has is the same in the end.
5 u - 9 = 3 u + 49
5 u - 3 u = 49 + 9
2 u = 58
1 u = 58 ÷ 2 = 29
Amount the girls have in the end
= 3 u + 49 + 5 u - 9
= 8 u + 40
= 8 x 29 + 40
= 232 + 40
= $272
Answer(s): $272
