15 as much money as Zara. Lucy received another $38 from her aunt and Zara spent $6 on some markers. In the end, Lucy and Zara had an equal amount of money. How much money did the girls have altogether in the end?

1 u |
5 u |

Change |
+ $38 |
- $6 |
|
After |
1 u + $38 |
5 u - $6 |
6 u + $32 |
Amount of money Lucy and Zara has is the same in the end.
5 u - 6 = 1 u + 38
5 u - 1 u = 38 + 6
4 u = 44
1 u = 44 ÷ 4 = 11
Amount the girls have in the end
= 1 u + 38 + 5 u - 6
= 6 u + 32
= 6 x 11 + 32
= 66 + 32
= $98
Answer(s): $98
