Before |
1 u + 120 |
1 u - 120 |
Change |
- 120 |
+ 120 |
After |
1 u |
1 u |
(a)
Total number of stickers
= 1 u + 1 u
= 2 u
2 u = 400
1 u = 400 ÷ 2 = 200
Number of stickers that Bryan has
= 1 u + 120
= 200 + 120
= 320
(b)
Number of stickers that Adam has
= 1 u - 120
= 200 - 120
= 80
Answer(s): (a) 320; (b) 80
