Bryan |
Adam |
Before |
1 u + 236 |
1 u - 26 |
Change |
- 26 |
+ 26 |
After |
1 u + 210 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 210
= 2 u + 210
2 u + 210 = 260
2 u = 260 - 210
2 u = 50
1 u = 50 ÷ 2 = 25
Number of stickers that Bryan has at first
= 1 u + 236
= 25 + 236
= 261
(b)
Number of stickers that Adam has in the end
= 1 u
= 25
Answer(s): (a) 261; (b) 25
