35 as much money as Zoe. Yoko received another $42 from her mother and Zoe spent $6 on some staplers. In the end, Yoko and Zoe had an equal amount of money. How much money did the girls have altogether in the end?

Before |
3 u |
5 u |
|
Change |
+ $42 |
- $6 |
|
After |
3 u + $42 |
5 u - $6 |
8 u + $36 |
Amount of money Yoko and Zoe has is the same in the end.
5 u - 6 = 3 u + 42
5 u - 3 u = 42 + 6
2 u = 48
1 u = 48 ÷ 2 = 24
Amount the girls have in the end
= 3 u + 42 + 5 u - 6
= 8 u + 36
= 8 x 24 + 36
= 192 + 36
= $228
Answer(s): $228
