Adam |
Before |
1 u + 174 |
1 u - 44 |
Change |
- 44 |
+ 44 |
After |
1 u + 130 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 130
= 2 u + 130
2 u + 130 = 440
2 u = 440 - 130
2 u = 310
1 u = 310 ÷ 2 = 155
Number of stickers that Bryan has at first
= 1 u + 174
= 155 + 174
= 329
(b)
Number of stickers that Adam has in the end
= 1 u
= 155
Answer(s): (a) 329; (b) 155
