Adam |
Before |
1 u + 157 |
1 u - 47 |
Change |
- 47 |
+ 47 |
After |
1 u + 110 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 110
= 2 u + 110
2 u + 110 = 470
2 u = 470 - 110
2 u = 360
1 u = 360 ÷ 2 = 180
Number of stickers that Bryan has at first
= 1 u + 157
= 180 + 157
= 337
(b)
Number of stickers that Adam has in the end
= 1 u
= 180
Answer(s): (a) 337; (b) 180
