2 u + 37 |
5 u + 9 |
If Erika received another $7 in the end, she would have the same amount of money as Hilda.
5 u + 9 + 7 = 2 u + 37
5 u + 16 = 2 u + 37
5 u - 2 u = 37 - 16
3 u = 21
1 u = 21 ÷ 3 = 7
Amount that the girls had in the end
= 2 u + 37 + 5 u + 9
= 2 u + 5 u + 37 + 9
= 7 u + 46
= 7 x 7 + 46
= $95
Answer(s): $95
