Adam |
Before |
1 u + 177 |
1 u - 37 |
Change |
- 37 |
+ 37 |
After |
1 u + 140 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 140
= 2 u + 140
2 u + 140 = 370
2 u = 370 - 140
2 u = 230
1 u = 230 ÷ 2 = 115
Number of stickers that Bryan has at first
= 1 u + 177
= 115 + 177
= 292
(b)
Number of stickers that Adam has in the end
= 1 u
= 115
Answer(s): (a) 292; (b) 115
