Pamela, Kimberly and Jade had a sum of money. The amount of money Pamela had was ³₄ of the amount of money Kimberly had. The ratio of the amount of money Kimberly had to the total amount of money Jade and Kimberly had was 3: 8. After Jade gave $4 to Kimberly, she had as much money as Kimberly. How much more money did Jade have than Pamela in the end?

Pamela	Kimberly	Jade
3x3 = 9 u	4x3 = 12 u
	3x4 = 12 u	5x4 = 20 u
9 u	12 u	20 u

The amount that Kimberly had is the repeated identity. Make the amount that Kimberly had the same.  LCM of 4 and 3 is 12.

	Pamela	Kimberly	Jade
Before	9 u	12 u	20 u
Change	No change	+ 4	- 4
After	9 u	12 u + 4	20 u - 4

The amount that Jade and Kimberly had in the end is the same.

20 u - 4 = 12 u + 4
20 u - 12 u = 4 + 4 
8 u = 8

1 u = 8 ÷ 8 = 1

Amount that Jade had more than Pamela in the end
= 20 u - 4 - 9 u
= 11 u - 4
= 11 x 1 - 4
= 11 - 4
= $7

Answer(s): $7
