| Before |
1 u |
8 u |
|
| Change |
+ $33 |
- $9 |
|
| After |
1 u + $33 |
8 u - $9 |
9 u + $24 |
Amount of money Elyse and Abi has is the same in the end.
8 u - 9 = 1 u + 33
8 u - 1 u = 33 + 9
7 u = 42
1 u = 42 ÷ 7 = 6
Amount the girls have in the end
= 1 u + 33 + 8 u - 9
= 9 u + 24
= 9 x 6 + 24
= 54 + 24
= $78
Answer(s): $78
