7 u |

Change |
+ $43 |
- $9 |
|
After |
3 u + $43 |
7 u - $9 |
10 u + $34 |
Amount of money Natalie and Hilda has is the same in the end.
7 u - 9 = 3 u + 43
7 u - 3 u = 43 + 9
4 u = 52
1 u = 52 ÷ 4 = 13
Amount the girls have in the end
= 3 u + 43 + 7 u - 9
= 10 u + 34
= 10 x 13 + 34
= 130 + 34
= $164
Answer(s): $164
