Bryan |
Adam |
Before |
1 u + 26 |
1 u - 6 |
Change |
- 6 |
+ 6 |
After |
1 u + 20 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 20
= 2 u + 20
2 u + 20 = 60
2 u = 60 - 20
2 u = 40
1 u = 40 ÷ 2 = 20
Number of stickers that Bryan has at first
= 1 u + 26
= 20 + 26
= 46
(b)
Number of stickers that Adam has in the end
= 1 u
= 20
Answer(s): (a) 46; (b) 20
