79 as much money as Xandra. Min received another $48 from her uncle and Xandra received $6 from her mother. In the end, Min had $2 more than Xandra. How much did the girls have altogether in the end?

+ 48 |
+ 6 |
| After |
7 u + 48 |
9 u + 6 |
If Xandra received another $2 in the end, she would have the same amount of money as Min.
9 u + 6 + 2 = 7 u + 48
9 u + 8 = 7 u + 48
9 u - 7 u = 48 - 8
2 u = 40
1 u = 40 ÷ 2 = 20
Amount that the girls had in the end
= 7 u + 48 + 9 u + 6
= 7 u + 9 u + 48 + 6
= 16 u + 54
= 16 x 20 + 54
= $374
Answer(s): $374
