37 as much money as Nicole. Anna received another $32 from her aunt and Nicole received $2 from her father. In the end, Anna had $2 more than Nicole. How much did the girls have altogether in the end?

+ 32 |
+ 2 |
| After |
3 u + 32 |
7 u + 2 |
If Nicole received another $2 in the end, she would have the same amount of money as Anna.
7 u + 2 + 2 = 3 u + 32
7 u + 4 = 3 u + 32
7 u - 3 u = 32 - 4
4 u = 28
1 u = 28 ÷ 4 = 7
Amount that the girls had in the end
= 3 u + 32 + 7 u + 2
= 3 u + 7 u + 32 + 2
= 10 u + 34
= 10 x 7 + 34
= $104
Answer(s): $104
