Adam |
Before |
1 u + 208 |
1 u - 38 |
Change |
- 38 |
+ 38 |
After |
1 u + 170 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 170
= 2 u + 170
2 u + 170 = 380
2 u = 380 - 170
2 u = 210
1 u = 210 ÷ 2 = 105
Number of stickers that Bryan has at first
= 1 u + 208
= 105 + 208
= 313
(b)
Number of stickers that Adam has in the end
= 1 u
= 105
Answer(s): (a) 313; (b) 105
