Change |
+ $29 |
- $6 |
|
After |
3 u + $29 |
8 u - $6 |
11 u + $23 |
Amount of money Lynn and Hilda has is the same in the end.
8 u - 6 = 3 u + 29
8 u - 3 u = 29 + 6
5 u = 35
1 u = 35 ÷ 5 = 7
Amount the girls have in the end
= 3 u + 29 + 8 u - 6
= 11 u + 23
= 11 x 7 + 23
= 77 + 23
= $100
Answer(s): $100
