Adam |
Before |
1 u + 84 |
1 u - 44 |
Change |
- 44 |
+ 44 |
After |
1 u + 40 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 40
= 2 u + 40
2 u + 40 = 440
2 u = 440 - 40
2 u = 400
1 u = 400 ÷ 2 = 200
Number of stickers that Bryan has at first
= 1 u + 84
= 200 + 84
= 284
(b)
Number of stickers that Adam has in the end
= 1 u
= 200
Answer(s): (a) 284; (b) 200
