Warren and Wesley had 101 stickers in total. Wesley had 45 stickers more than Warren at first. After Warren and Wesley played a game with Jen, Warren had ²₁₁ as many stickers as Wesley. If Warren lost as many stickers as Wesley to Jen, find the number of stickers that Warren lost to Jen.

	Warren	Wesley	Difference
Before	1 u	1 u + 45	45
Change	- ?	- ?
After	2 p	11 p	9 p

Total number of stickers at first
= 1 u + 1 u + 45 
= 2 u + 45

2 u + 45 = 101
2 u = 101 - 45
2 u = 56

1 u = 56 ÷ 2 = 28

Since Warren lost the same number of stickers as Wesley, the difference in the number of stickers between Warren and Wesley at first and in the end remains the same.

Difference in the number of stickers in the end
= 11 p - 2 p
= 9 p

9 p = 45

1 p = 45 ÷ 9 = 5

Number of stickers that Warren lost to Jen
= 1 u - 2 p
= 28 - 2 x 5
= 28 - 10
= 18

Answer(s): 18
