| After |
9 u + 48 |
11 u + 3 |
If Emma received another $9 in the end, she would have the same amount of money as Anna.
11 u + 3 + 9 = 9 u + 48
11 u + 12 = 9 u + 48
11 u - 9 u = 48 - 12
2 u = 36
1 u = 36 ÷ 2 = 18
Amount that the girls had in the end
= 9 u + 48 + 11 u + 3
= 9 u + 11 u + 48 + 3
= 20 u + 51
= 20 x 18 + 51
= $411
Answer(s): $411
