Total |
Before |
1 u + 100 |
1 u - 100 |
6000 |
Change |
- 100 |
+ 100 |
|
After |
1 u |
1 u |
2 u |
(a)
In the end
Number of stickers that Bryan has = 1 u
Number of stickers that Adam has = 1 u
Total number of stickers = 1 u + 1 u = 2 u
At first
Number of stickers that Bryan has = 1 u + 100
Number of stickers that Adam has = 1 u - 100
2 u = 6000
1 u = 6000 ÷ 2 = 3000
Number of stickers that Adam has at first
= 1 u - 100
= 3000 - 100
= 2900
(b)
Number of stickers that each has in the end
= 1 u
= 3000
Answer(s): (a) 2900; (b) 3000
