Adam |
Before |
1 u + 260 |
1 u - 30 |
Change |
- 30 |
+ 30 |
After |
1 u + 230 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 230
= 2 u + 230
2 u + 230 = 300
2 u = 300 - 230
2 u = 70
1 u = 70 ÷ 2 = 35
Number of stickers that Bryan has at first
= 1 u + 260
= 35 + 260
= 295
(b)
Number of stickers that Adam has in the end
= 1 u
= 35
Answer(s): (a) 295; (b) 35
