Adam |
Before |
1 u + 94 |
1 u - 24 |
Change |
- 24 |
+ 24 |
After |
1 u + 70 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 70
= 2 u + 70
2 u + 70 = 240
2 u = 240 - 70
2 u = 170
1 u = 170 ÷ 2 = 85
Number of stickers that Bryan has at first
= 1 u + 94
= 85 + 94
= 179
(b)
Number of stickers that Adam has in the end
= 1 u
= 85
Answer(s): (a) 179; (b) 85
