6 u + 48 |
11 u + 9 |
If Betty received another $4 in the end, she would have the same amount of money as Gillian.
11 u + 9 + 4 = 6 u + 48
11 u + 13 = 6 u + 48
11 u - 6 u = 48 - 13
5 u = 35
1 u = 35 ÷ 5 = 7
Amount that the girls had in the end
= 6 u + 48 + 11 u + 9
= 6 u + 11 u + 48 + 9
= 17 u + 57
= 17 x 7 + 57
= $176
Answer(s): $176
