Bryan |
Adam |
Before |
1 u + 196 |
1 u - 26 |
Change |
- 26 |
+ 26 |
After |
1 u + 170 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 170
= 2 u + 170
2 u + 170 = 260
2 u = 260 - 170
2 u = 90
1 u = 90 ÷ 2 = 45
Number of stickers that Bryan has at first
= 1 u + 196
= 45 + 196
= 241
(b)
Number of stickers that Adam has in the end
= 1 u
= 45
Answer(s): (a) 241; (b) 45
