Victoria and Jaslyn collected stickers. Victoria gave 30% of her stickers to Jaslyn and as a result, Jaslyn's stickers increased by 25%. If Victoria had 42 stickers left, find the number of stickers Jaslyn should give to Victoria in the end so that both had an equal number of stickers.

	Victoria	Jaslyn	Comparing the change in Jaslyn's stickers
Before	10x1 = 10 u		4x3 = 12u
Change	- 3x1 = - 3 u	+ 3x1 = + 3 u	+ 1x3 = + 3 u
After	7x1 = 7 u		5x3 = 15 u

30% = ³⁰₁₀₀ = ³₁₀
25% = ²⁵₁₀₀ = ¹₄

The increase in the number of stickers that Jaslyn had is repeated.  Make the increase in the number of stickers that Jaslyn had the same. LCM of 3 and 1 = 3

7 u = 42

1 u = 42 ÷ 7 = 6

Number of stickers that Jaslyn had more than Victoria in the end
= 15 u - 7 u
= 8 u

Number of stickers that Jaslyn should give to Victoria so that both had an equal number of stickers in the end
= 8 u ÷ 2
= 4 u
= 4 x 6
= 24

Answer(s): 24
