Adam |
Before |
1 u + 307 |
1 u - 47 |
Change |
- 47 |
+ 47 |
After |
1 u + 260 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 260
= 2 u + 260
2 u + 260 = 470
2 u = 470 - 260
2 u = 210
1 u = 210 ÷ 2 = 105
Number of stickers that Bryan has at first
= 1 u + 307
= 105 + 307
= 412
(b)
Number of stickers that Adam has in the end
= 1 u
= 105
Answer(s): (a) 412; (b) 105
