Adam |
Before |
1 u + 98 |
1 u - 38 |
Change |
- 38 |
+ 38 |
After |
1 u + 60 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 60
= 2 u + 60
2 u + 60 = 380
2 u = 380 - 60
2 u = 320
1 u = 320 ÷ 2 = 160
Number of stickers that Bryan has at first
= 1 u + 98
= 160 + 98
= 258
(b)
Number of stickers that Adam has in the end
= 1 u
= 160
Answer(s): (a) 258; (b) 160
