Bryan |
Before |
1 u + 191 |
1 u - 41 |
Change |
- 41 |
+ 41 |
After |
1 u + 150 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 150
= 2 u + 150
2 u + 150 = 410
2 u = 410 - 150
2 u = 260
1 u = 260 ÷ 2 = 130
Number of stickers that Adam has at first
= 1 u + 191
= 130 + 191
= 321
(b)
Number of stickers that Bryan has in the end
= 1 u
= 130
Answer(s): (a) 321; (b) 130
