Mary, Jaslyn and Risa shared $240 among themselves. Jaslyn and Risa shared ²₅ of the money equally. After Jaslyn gave away some of her money to Mary, Risa had 6 times as much money as Jaslyn. How much money did Jaslyn give to Mary?

	Jaslyn	Risa	Mary	Total
Before	1x6 = 6 u	1x6 = 6 u	3x6 = 18 u	30 u
Change	- 5 u	No change	+ 5 u
After	1x1 = 1 u	6x1 = 6 u	23 u	30 u

Jaslyn and Risa shared ²₅ of the money equally.

Fraction of the money that Jaslyn and Risa each had
= ²₅ ÷ 2
= ²₅ x ¹₂
= ¹₅

The amount that Risa had remains unchanged.  The amount that Risa had is the unchanged quantity. Make the amount that Risa had the same. LCM of 1 and 6 is 6.

The amount that Jaslyn and Risa had at first is the same.

Total amount that they had at first
= 6 u + 6 u + 18 u
= 30 u

30 u = 240

1 u = 240 ÷ 30 = 8

Amount that Jaslyn gave to Mary
= 6 u - 1 u
= 5 u
= 5 x 8
= $40

Answer(s): $40
