Bryan |
Before |
1 u + 156 |
1 u - 46 |
Change |
- 46 |
+ 46 |
After |
1 u + 110 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 110
= 2 u + 110
2 u + 110 = 460
2 u = 460 - 110
2 u = 350
1 u = 350 ÷ 2 = 175
Number of stickers that Adam has at first
= 1 u + 156
= 175 + 156
= 331
(b)
Number of stickers that Bryan has in the end
= 1 u
= 175
Answer(s): (a) 331; (b) 175
