Bryan |
Before |
1 u + 126 |
1 u - 26 |
Change |
- 26 |
+ 26 |
After |
1 u + 100 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 100
= 2 u + 100
2 u + 100 = 260
2 u = 260 - 100
2 u = 160
1 u = 160 ÷ 2 = 80
Number of stickers that Adam has at first
= 1 u + 126
= 80 + 126
= 206
(b)
Number of stickers that Bryan has in the end
= 1 u
= 80
Answer(s): (a) 206; (b) 80
