Adam |
Before |
1 u + 236 |
1 u - 46 |
Change |
- 46 |
+ 46 |
After |
1 u + 190 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 190
= 2 u + 190
2 u + 190 = 460
2 u = 460 - 190
2 u = 270
1 u = 270 ÷ 2 = 135
Number of stickers that Bryan has at first
= 1 u + 236
= 135 + 236
= 371
(b)
Number of stickers that Adam has in the end
= 1 u
= 135
Answer(s): (a) 371; (b) 135
