Adam |
Before |
1 u + 44 |
1 u - 34 |
Change |
- 34 |
+ 34 |
After |
1 u + 10 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 10
= 2 u + 10
2 u + 10 = 340
2 u = 340 - 10
2 u = 330
1 u = 330 ÷ 2 = 165
Number of stickers that Bryan has at first
= 1 u + 44
= 165 + 44
= 209
(b)
Number of stickers that Adam has in the end
= 1 u
= 165
Answer(s): (a) 209; (b) 165
