35 as much money as Rachel. Zara received another $34 from her mother and Rachel spent $12 on some staplers. In the end, Zara and Rachel had an equal amount of money. How much money did the girls have altogether in the end?

Before |
3 u |
5 u |
|
Change |
+ $34 |
- $12 |
|
After |
3 u + $34 |
5 u - $12 |
8 u + $22 |
Amount of money Zara and Rachel has is the same in the end.
5 u - 12 = 3 u + 34
5 u - 3 u = 34 + 12
2 u = 46
1 u = 46 ÷ 2 = 23
Amount the girls have in the end
= 3 u + 34 + 5 u - 12
= 8 u + 22
= 8 x 23 + 22
= 184 + 22
= $206
Answer(s): $206
