Adam |
Before |
1 u + 301 |
1 u - 41 |
Change |
- 41 |
+ 41 |
After |
1 u + 260 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 260
= 2 u + 260
2 u + 260 = 410
2 u = 410 - 260
2 u = 150
1 u = 150 ÷ 2 = 75
Number of stickers that Bryan has at first
= 1 u + 301
= 75 + 301
= 376
(b)
Number of stickers that Adam has in the end
= 1 u
= 75
Answer(s): (a) 376; (b) 75
