Adam |
Before |
1 u + 147 |
1 u - 37 |
Change |
- 37 |
+ 37 |
After |
1 u + 110 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 110
= 2 u + 110
2 u + 110 = 370
2 u = 370 - 110
2 u = 260
1 u = 260 ÷ 2 = 130
Number of stickers that Bryan has at first
= 1 u + 147
= 130 + 147
= 277
(b)
Number of stickers that Adam has in the end
= 1 u
= 130
Answer(s): (a) 277; (b) 130
