Total |
Before |
1 u + 300 |
1 u - 300 |
1000 |
Change |
- 300 |
+ 300 |
|
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 + 300
Number of stickers that Adam has = 1 u - 300
2 u = 1000
1 u = 1000 ÷ 2 = 500
Number of stickers that Bryan has at first
= 1 u + 300
= 500 + 300
= 800
(b)
Number of stickers that each has in the end
= 1 u
= 500
Answer(s): (a) 800; (b) 500
