Lynn's and Julie's savings were in the ratio of 4 : 9. Both of them shared the cost of their cousin's souvenir equally. Lynn's remaining savings was ¹₅ as much as Julie's savings. What percentage of her savings did Julie spend? Correct the answer to 1 decimal place.

	Lynn	Julie	Difference
Before	4x4 = 16 u	9x4 = 36 u	5x4 = 20 u
Change	- 11 u	- 11 u
After	1x5 = 5 u	5x5 = 25 u	4x5 = 20 u

Since Lynn and Julie shared the cost of their cousin's souvenir equally, the amount each paid for the souvenir is the same. 

So, the difference in the amounts between Lynn and Julie at first and in the end remains the same.  Make the difference in the amounts between Lynn and Julie at first and in the end the same. LCM of 5 and 4 is 20.

Amount that Julie spent on the souvenir
= 36 u - 25 u
= 11 u

Percentage of her savings that Julie spent
= ¹¹₃₆ x 100%
≈ 30.6%

Answer(s): 30.6%
