Kathy and Lynn collected stickers. Kathy gave 60% of her stickers to Lynn and as a result, Lynn's stickers increased by 20%. If Kathy had 14 stickers left, find the number of stickers Lynn should give to Kathy in the end so that both had an equal number of stickers.

	Kathy	Lynn	Comparing the change in Lynn's stickers
Before	5x1 = 5 u		5x3 = 15u
Change	- 3x1 = - 3 u	+ 3x1 = + 3 u	+ 1x3 = + 3 u
After	2x1 = 2 u		6x3 = 18 u

60% = ⁶⁰₁₀₀ = ³₅
20% = ²⁰₁₀₀ = ¹₅

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

2 u = 14

1 u = 14 ÷ 2 = 7

Number of stickers that Lynn had more than Kathy in the end
= 18 u - 2 u
= 16 u

Number of stickers that Lynn should give to Kathy so that both had an equal number of stickers in the end
= 16 u ÷ 2
= 8 u
= 8 x 7
= 56

Answer(s): 56
