Eva, Jean and Min had a sum of money. The amount of money Eva had was ²₅ of the amount of money Jean had. The ratio of the amount of money Jean had to the total amount of money Min and Jean had was 2: 5. After Min gave $35 to Jean, she had as much money as Jean. How much more money did Min have than Eva in the end?

Eva	Jean	Min
2x2 = 4 u	5x2 = 10 u
	2x5 = 10 u	3x5 = 15 u
4 u	10 u	15 u

The amount that Jean had is the repeated identity. Make the amount that Jean had the same.  LCM of 5 and 2 is 10.

	Eva	Jean	Min
Before	4 u	10 u	15 u
Change	No change	+ 35	- 35
After	4 u	10 u + 35	15 u - 35

The amount that Min and Jean had in the end is the same.

15 u - 35 = 10 u + 35
15 u - 10 u = 35 + 35 
5 u = 70

1 u = 70 ÷ 5 = 14

Amount that Min had more than Eva in the end
= 15 u - 35 - 4 u
= 11 u - 35
= 11 x 14 - 35
= 154 - 35
= $119

Answer(s): $119
