Bryan |
Before |
1 u + 283 |
1 u - 33 |
Change |
- 33 |
+ 33 |
After |
1 u + 250 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 250
= 2 u + 250
2 u + 250 = 330
2 u = 330 - 250
2 u = 80
1 u = 80 ÷ 2 = 40
Number of stickers that Adam has at first
= 1 u + 283
= 40 + 283
= 323
(b)
Number of stickers that Bryan has in the end
= 1 u
= 40
Answer(s): (a) 323; (b) 40
