Bryan |
Adam |
Before |
1 u + 156 |
1 u - 16 |
Change |
- 16 |
+ 16 |
After |
1 u + 140 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 140
= 2 u + 140
2 u + 140 = 160
2 u = 160 - 140
2 u = 20
1 u = 20 ÷ 2 = 10
Number of stickers that Bryan has at first
= 1 u + 156
= 10 + 156
= 166
(b)
Number of stickers that Adam has in the end
= 1 u
= 10
Answer(s): (a) 166; (b) 10
