Nicole, Tammy and Jaslyn shared $225 among themselves. Tammy and Jaslyn shared ²₅ of the money equally. After Tammy gave away some of her money to Nicole, Jaslyn had 3 times as much money as Tammy. How much money did Tammy give to Nicole?

	Tammy	Jaslyn	Nicole	Total
Before	1x3 = 3 u	1x3 = 3 u	3x3 = 9 u	15 u
Change	- 2 u	No change	+ 2 u
After	1x1 = 1 u	3x1 = 3 u	11 u	15 u

Tammy and Jaslyn shared ²₅ of the money equally.

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

The amount that Jaslyn had remains unchanged.  The amount that Jaslyn had is the unchanged quantity. Make the amount that Jaslyn had the same. LCM of 1 and 3 is 3.

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

Total amount that they had at first
= 3 u + 3 u + 9 u
= 15 u

15 u = 225

1 u = 225 ÷ 15 = 15

Amount that Tammy gave to Nicole
= 3 u - 1 u
= 2 u
= 2 x 15
= $30

Answer(s): $30
