Bryan |
Adam |
Before |
1 u + 203 |
1 u - 23 |
Change |
- 23 |
+ 23 |
After |
1 u + 180 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 180
= 2 u + 180
2 u + 180 = 230
2 u = 230 - 180
2 u = 50
1 u = 50 ÷ 2 = 25
Number of stickers that Bryan has at first
= 1 u + 203
= 25 + 203
= 228
(b)
Number of stickers that Adam has in the end
= 1 u
= 25
Answer(s): (a) 228; (b) 25
