35 as much money as Min. Penelope received another $25 from her aunt and Min spent $11 on some staplers. In the end, Penelope and Min had an equal amount of money. How much money did the girls have altogether in the end?

5 u |
|
Change |
+ $25 |
- $11 |
|
After |
3 u + $25 |
5 u - $11 |
8 u + $14 |
Amount of money Penelope and Min has is the same in the end.
5 u - 11 = 3 u + 25
5 u - 3 u = 25 + 11
2 u = 36
1 u = 36 ÷ 2 = 18
Amount the girls have in the end
= 3 u + 25 + 5 u - 11
= 8 u + 14
= 8 x 18 + 14
= 144 + 14
= $158
Answer(s): $158
