Bryan |
Before |
1 u + 243 |
1 u - 33 |
Change |
- 33 |
+ 33 |
After |
1 u + 210 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 210
= 2 u + 210
2 u + 210 = 330
2 u = 330 - 210
2 u = 120
1 u = 120 ÷ 2 = 60
Number of stickers that Adam has at first
= 1 u + 243
= 60 + 243
= 303
(b)
Number of stickers that Bryan has in the end
= 1 u
= 60
Answer(s): (a) 303; (b) 60
