Bryan |
Before |
1 u + 204 |
1 u - 34 |
Change |
- 34 |
+ 34 |
After |
1 u + 170 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 170
= 2 u + 170
2 u + 170 = 340
2 u = 340 - 170
2 u = 170
1 u = 170 ÷ 2 = 85
Number of stickers that Adam has at first
= 1 u + 204
= 85 + 204
= 289
(b)
Number of stickers that Bryan has in the end
= 1 u
= 85
Answer(s): (a) 289; (b) 85
