Adam |
Bryan |
Before |
1 u + 56 |
1 u - 6 |
Change |
- 6 |
+ 6 |
After |
1 u + 50 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 50
= 2 u + 50
2 u + 50 = 60
2 u = 60 - 50
2 u = 10
1 u = 10 ÷ 2 = 5
Number of stickers that Adam has at first
= 1 u + 56
= 5 + 56
= 61
(b)
Number of stickers that Bryan has in the end
= 1 u
= 5
Answer(s): (a) 61; (b) 5
