Adam |
Before |
1 u + 366 |
1 u - 46 |
Change |
- 46 |
+ 46 |
After |
1 u + 320 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 320
= 2 u + 320
2 u + 320 = 460
2 u = 460 - 320
2 u = 140
1 u = 140 ÷ 2 = 70
Number of stickers that Bryan has at first
= 1 u + 366
= 70 + 366
= 436
(b)
Number of stickers that Adam has in the end
= 1 u
= 70
Answer(s): (a) 436; (b) 70
