Shannon, Lynn and Elyse had a sum of money. The amount of money Shannon had was
34 of the amount of money Lynn had. The ratio of the amount of money Lynn had to the total amount of money Elyse and Lynn had was 2: 5. After Elyse gave $23 to Lynn, she had as much money as Lynn. How much more money did Elyse have than Shannon in the end?

Lynn |
Elyse |
3x1 = 3 u |
4x1 = 4 u |
|
|
2x2 = 4 u |
3x2 = 6 u |
3 u |
4 u |
6 u |
The amount that Lynn had is the repeated identity. Make the amount that Lynn had the same. LCM of 4 and 2 is 4.

+ 23 |
- 23 |
After |
3 u |
4 u + 23 |
6 u - 23 |
The amount that Elyse and Lynn had in the end is the same.
6 u - 23 = 4 u + 23
6 u - 4 u = 23 + 23
2 u = 46
1 u = 46 ÷ 2 = 23
Amount that Elyse had more than Shannon in the end
= 6 u - 23 - 3 u
= 3 u - 23
= 3 x 23 - 23
= 69 - 23
= $46
Answer(s): $46
