| After |
5 u + 44 |
8 u + 4 |
If Zoe received another $4 in the end, she would have the same amount of money as Barbara.
8 u + 4 + 4 = 5 u + 44
8 u + 8 = 5 u + 44
8 u - 5 u = 44 - 8
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that the girls had in the end
= 5 u + 44 + 8 u + 4
= 5 u + 8 u + 44 + 4
= 13 u + 48
= 13 x 12 + 48
= $204
Answer(s): $204
