Total |
Before |
1 u + 700 |
1 u - 700 |
2000 |
Change |
- 700 |
+ 700 |
|
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 + 700
Number of stickers that Adam has = 1 u - 700
2 u = 2000
1 u = 2000 ÷ 2 = 1000
Number of stickers that Bryan has at first
= 1 u + 700
= 1000 + 700
= 1700
(b)
Number of stickers that each has in the end
= 1 u
= 1000
Answer(s): (a) 1700; (b) 1000
