Bryan |
Before |
1 u + 275 |
1 u - 35 |
Change |
- 35 |
+ 35 |
After |
1 u + 240 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 240
= 2 u + 240
2 u + 240 = 350
2 u = 350 - 240
2 u = 110
1 u = 110 ÷ 2 = 55
Number of stickers that Adam has at first
= 1 u + 275
= 55 + 275
= 330
(b)
Number of stickers that Bryan has in the end
= 1 u
= 55
Answer(s): (a) 330; (b) 55
