Total |
| Before |
3 u |
10 u |
|
| Change |
+ $39 |
- $10 |
|
| After |
3 u + $39 |
10 u - $10 |
13 u + $29 |
Amount of money Min and Elyse has is the same in the end.
10 u - 10 = 3 u + 39
10 u - 3 u = 39 + 10
7 u = 49
1 u = 49 ÷ 7 = 7
Amount the girls have in the end
= 3 u + 39 + 10 u - 10
= 13 u + 29
= 13 x 7 + 29
= 91 + 29
= $120
Answer(s): $120
