Bryan |
Before |
1 u + 186 |
1 u - 36 |
Change |
- 36 |
+ 36 |
After |
1 u + 150 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 150
= 2 u + 150
2 u + 150 = 360
2 u = 360 - 150
2 u = 210
1 u = 210 ÷ 2 = 105
Number of stickers that Adam has at first
= 1 u + 186
= 105 + 186
= 291
(b)
Number of stickers that Bryan has in the end
= 1 u
= 105
Answer(s): (a) 291; (b) 105
