After |
4 u + 36 |
7 u + 3 |
If Raeann received another $3 in the end, she would have the same amount of money as Esther.
7 u + 3 + 3 = 4 u + 36
7 u + 6 = 4 u + 36
7 u - 4 u = 36 - 6
3 u = 30
1 u = 30 ÷ 3 = 10
Amount that the girls had in the end
= 4 u + 36 + 7 u + 3
= 4 u + 7 u + 36 + 3
= 11 u + 39
= 11 x 10 + 39
= $149
Answer(s): $149
