Adam has 800 stickers more than Bryan.
Adam gives Bryan 100 stickers.
Now, Adam has 6 times as many stickers as Bryan.

1. How many stickers does Adam have in the end?
2. How many stickers does Bryan have in the end?

	Adam	Bryan
Before	6 u + 100	1 u - 100
Change	- 100	+ 100
After	6 u	1 u

(a)
At first
Number of stickers that Adam has = 6 u + 100
Number of stickers that Bryan has = 1 u - 100

In the end
Number of stickers that Adam has = 6 u 
Number of stickers that Bryan has = 1 u 

If the number of stickers that Bryan has at first increases by 800, he will have as many stickers as Adam at first.

6 u + 100 = 1 u - 100 + 800
6 u + 100 = 1 u + 700
6 u - 1 u = 700 - 100
5 u = 600

1 u = 600 ÷ 5 = 120

Number of stickers that Adam in the end
= 6 u 
= 6 x 120
= 720

(b)
Number of stickers that Bryan has in the end
= 1 u 
= 120

Answer(s): (a) 720; (b) 120
