Adam |
Before |
1 u + 325 |
1 u - 35 |
Change |
- 35 |
+ 35 |
After |
1 u + 290 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 290
= 2 u + 290
2 u + 290 = 350
2 u = 350 - 290
2 u = 60
1 u = 60 ÷ 2 = 30
Number of stickers that Bryan has at first
= 1 u + 325
= 30 + 325
= 355
(b)
Number of stickers that Adam has in the end
= 1 u
= 30
Answer(s): (a) 355; (b) 30
