Total |
| Before |
1 u |
7 u |
|
| Change |
+ $34 |
- $8 |
|
| After |
1 u + $34 |
7 u - $8 |
8 u + $26 |
Amount of money Xuan and Gillian has is the same in the end.
7 u - 8 = 1 u + 34
7 u - 1 u = 34 + 8
6 u = 42
1 u = 42 ÷ 6 = 7
Amount the girls have in the end
= 1 u + 34 + 7 u - 8
= 8 u + 26
= 8 x 7 + 26
= 56 + 26
= $82
Answer(s): $82
