| After |
5 u + 30 |
8 u + 4 |
If Sarah received another $2 in the end, she would have the same amount of money as Hilda.
8 u + 4 + 2 = 5 u + 30
8 u + 6 = 5 u + 30
8 u - 5 u = 30 - 6
3 u = 24
1 u = 24 ÷ 3 = 8
Amount that the girls had in the end
= 5 u + 30 + 8 u + 4
= 5 u + 8 u + 30 + 4
= 13 u + 34
= 13 x 8 + 34
= $138
Answer(s): $138
