Emma had the same number of silver, pink and black stickers at first. After giving some silver and pink stickers and 50 black stickers away, Emma had 229 stickers left. There were 4 times as many silver stickers as pink stickers left. The number of black stickers left was 32 fewer than the number of silver stickers left. How many black stickers did she have at first?

	Pink	Silver	Black	Total
Before	4 u + 18	4 u + 18	4 u + 18
Change	- 3 u - 18	- 18	- 50
After	1 u	4 u	4 u - 32	229

Emma had the same number of silver, pink and black stickers at first.

Total number of stickers in the end
= 1 u + 4 u + 4 u - 32
= 9 u - 32

9 u - 32 = 229
9 u = 229 + 32
9 u = 261

1 u = 261 ÷ 9 = 29

Number of black stickers that Emma had at first
= 4 u - 32 + 50
= 4 u + 18
= 4 x 29 + 18
= 134

Answer(s): 134
