Adam |
Before |
1 u + 367 |
1 u - 37 |
Change |
- 37 |
+ 37 |
After |
1 u + 330 |
1 u |
(a)
Total number of stickers
= 1 u + 1 u + 330
= 2 u + 330
2 u + 330 = 370
2 u = 370 - 330
2 u = 40
1 u = 40 ÷ 2 = 20
Number of stickers that Bryan has at first
= 1 u + 367
= 20 + 367
= 387
(b)
Number of stickers that Adam has in the end
= 1 u
= 20
Answer(s): (a) 387; (b) 20
