| After |
5 u + 34 |
7 u + 7 |
If Abi received another $3 in the end, she would have the same amount of money as Joelle.
7 u + 7 + 3 = 5 u + 34
7 u + 10 = 5 u + 34
7 u - 5 u = 34 - 10
2 u = 24
1 u = 24 ÷ 2 = 12
Amount that the girls had in the end
= 5 u + 34 + 7 u + 7
= 5 u + 7 u + 34 + 7
= 12 u + 41
= 12 x 12 + 41
= $185
Answer(s): $185
