Bryan |
Adam |
Before |
1 u + 189 |
1 u - 29 |
Change |
- 29 |
+ 29 |
After |
1 u + 160 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 160
= 2 u + 160
2 u + 160 = 290
2 u = 290 - 160
2 u = 130
1 u = 130 ÷ 2 = 65
Number of stickers that Bryan has at first
= 1 u + 189
= 65 + 189
= 254
(b)
Number of stickers that Adam has in the end
= 1 u
= 65
Answer(s): (a) 254; (b) 65
