Before |
1 u + 146 |
1 u - 36 |
Change |
- 36 |
+ 36 |
After |
1 u + 110 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 110
= 2 u + 110
2 u + 110 = 360
2 u = 360 - 110
2 u = 250
1 u = 250 ÷ 2 = 125
Number of stickers that Adam has at first
= 1 u + 146
= 125 + 146
= 271
(b)
Number of stickers that Bryan has in the end
= 1 u
= 125
Answer(s): (a) 271; (b) 125
