Zara had
35 as much money as Nicole. Zara received another $29 from her uncle and Nicole spent $9 on some pens. In the end, Zara and Nicole had an equal amount of money. How much money did the girls have altogether in the end?

5 u |
|
Change |
+ $29 |
- $9 |
|
After |
3 u + $29 |
5 u - $9 |
8 u + $20 |
Amount of money Zara and Nicole has is the same in the end.
5 u - 9 = 3 u + 29
5 u - 3 u = 29 + 9
2 u = 38
1 u = 38 ÷ 2 = 19
Amount the girls have in the end
= 3 u + 29 + 5 u - 9
= 8 u + 20
= 8 x 19 + 20
= 152 + 20
= $172
Answer(s): $172
