Bryan |
Before |
1 u + 276 |
1 u - 26 |
Change |
- 26 |
+ 26 |
After |
1 u + 250 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 250
= 2 u + 250
2 u + 250 = 260
2 u = 260 - 250
2 u = 10
1 u = 10 ÷ 2 = 5
Number of stickers that Adam has at first
= 1 u + 276
= 5 + 276
= 281
(b)
Number of stickers that Bryan has in the end
= 1 u
= 5
Answer(s): (a) 281; (b) 5
