Gabby and Jaslyn had 858 stickers altogether. They decided to play a game. In the first round, Jaslyn lost 58 stickers to Gabby. In the second round, Gabby lost 31 stickers to Jaslyn. At the end of the two rounds, Jaslyn had five times as many stickers as Gabby.

1. How many stickers did Gabby have in the end?
2. How many stickers did Jaslyn have at the beginning of the game?

	Gabby	Jaslyn	Total
Before	1 u + 31 - 58	5 u - 31 + 58	858
Round 1	+ 58	- 58
Round 2	- 31	+ 31
After	1 u	5 u	858

(a)
Total number of stickers
= 1 u + 5 u
= 6 u

6 u = 858

1 u = 858 ÷ 6 = 143

Number of stickers that Gabby had in the end
= 1 u
= 143

(b)
Working backwards.

Number of stickers that Jaslyn had at the end of round 2
= 5 u
= 5 x 143
= 715

Number of stickers that Jaslyn had at the end of round 1
= 715 - 31
= 684

Number of stickers that Jaslyn had at the beginning of the game
= 684 + 58
= 742

Answer(s): (a) 143; (b) 742
