| After |
5 u + 41 |
9 u + 5 |
If Risa received another $8 in the end, she would have the same amount of money as Sabrina.
9 u + 5 + 8 = 5 u + 41
9 u + 13 = 5 u + 41
9 u - 5 u = 41 - 13
4 u = 28
1 u = 28 ÷ 4 = 7
Amount that the girls had in the end
= 5 u + 41 + 9 u + 5
= 5 u + 9 u + 41 + 5
= 14 u + 46
= 14 x 7 + 46
= $144
Answer(s): $144
