Roshel, Jade and Shiyun bought a souvenir for their nephew. They shared the cost equally between them. Roshel used ³₈ of her savings, Jade used ⁵₉ of her savings and Shiyun used ²₅ of her savings. Roshel and Shiyun had $1615 left. How much did each girl pay for the souvenir?
The amount spent by each girl is the same.  Make the numerators the same.
LCM of 3, 5 and 2 = 30

3x108x10 of Roshel's savings = 5x69x6 of Jade's savings = 2x155x15 of Shiyun savings
3080 of Roshel's savings = 3054 of Jade's savings = 3075 of Shiyun's savings

	Roshel	Jade	Shiyun
Before	80 u	54 u	75 u
Change	- 30 u	- 30 u	- 30 u
After	50 u	24 u	45 u

Savings that Roshel had left
= 80 u - 30 u
= 50 u

Savings that Shiyun had left
= 75 u - 30 u
= 45 u

Total savings that Roshel and Shiyun had left
= 50 u + 45 u
= 95 u

95 u = 1615

1 u = 1615 ÷ 95 = 17

Amount that each girl paid
= 30 u
= 30 x 17
= $510

Answer(s): $510
