7 u |
|
Change |
+ $26 |
- $6 |
|
After |
3 u + $26 |
7 u - $6 |
10 u + $20 |
Amount of money Gillian and Hilda has is the same in the end.
7 u - 6 = 3 u + 26
7 u - 3 u = 26 + 6
4 u = 32
1 u = 32 ÷ 4 = 8
Amount the girls have in the end
= 3 u + 26 + 7 u - 6
= 10 u + 20
= 10 x 8 + 20
= 80 + 20
= $100
Answer(s): $100
