Bryan |
Adam |
Before |
1 u + 193 |
1 u - 33 |
Change |
- 33 |
+ 33 |
After |
1 u + 160 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 160
= 2 u + 160
2 u + 160 = 330
2 u = 330 - 160
2 u = 170
1 u = 170 ÷ 2 = 85
Number of stickers that Bryan has at first
= 1 u + 193
= 85 + 193
= 278
(b)
Number of stickers that Adam has in the end
= 1 u
= 85
Answer(s): (a) 278; (b) 85
