Before |
1 u + 130 |
1 u - 130 |
Change |
- 130 |
+ 130 |
After |
1 u |
1 u |
(a)
Total number of stickers
= 1 u + 1 u
= 2 u
2 u = 500
1 u = 500 ÷ 2 = 250
Number of stickers that Bryan has
= 1 u + 130
= 250 + 130
= 380
(b)
Number of stickers that Adam has
= 1 u - 130
= 250 - 130
= 120
Answer(s): (a) 380; (b) 120
