Before |
1 u + 100 |
1 u - 100 |
Change |
- 100 |
+ 100 |
After |
1 u |
1 u |
(a)
Total number of stickers
= 1 u + 1 u
= 2 u
2 u = 400
1 u = 400 ÷ 2 = 200
Number of stickers that Bryan has
= 1 u + 100
= 200 + 100
= 300
(b)
Number of stickers that Adam has
= 1 u - 100
= 200 - 100
= 100
Answer(s): (a) 300; (b) 100
