Bryan |
Before |
1 u + 232 |
1 u - 22 |
Change |
- 22 |
+ 22 |
After |
1 u + 210 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 210
= 2 u + 210
2 u + 210 = 220
2 u = 220 - 210
2 u = 10
1 u = 10 ÷ 2 = 5
Number of stickers that Adam has at first
= 1 u + 232
= 5 + 232
= 237
(b)
Number of stickers that Bryan has in the end
= 1 u
= 5
Answer(s): (a) 237; (b) 5
