| After |
3 u + 35 |
5 u + 2 |
If Gem received another $5 in the end, she would have the same amount of money as Emily.
5 u + 2 + 5 = 3 u + 35
5 u + 7 = 3 u + 35
5 u - 3 u = 35 - 7
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that the girls had in the end
= 3 u + 35 + 5 u + 2
= 3 u + 5 u + 35 + 2
= 8 u + 37
= 8 x 14 + 37
= $149
Answer(s): $149
