Lee |
Zeph |
Chan |
| Before |
10 u |
6 u |
7 u |
| Change |
+ 2.2 u |
+ 2.7 u |
- 4.9 u |
| After |
12.2 u |
8.7 u |
2.1 u |
Number of stickers that Chan gave to Lee and Zeph
=
710 x 7 u
= 4.9 u
Number of stickers that Zeph received from Chan
=
45100 x 6 u
= 2.7 u
Number of stickers that Lee received from Chan
= 4.9 u - 2.7 u
= 2.2 u
Number of less stickers that Chan had less than Lee
= 12.2 u - 2.1 u
= 10.1 u
10.1 u = 101
1 u = 101 ÷ 10.1 = 10
Number of stickers that Lee and Chan had
= 12.2 u + 2.1 u
= 14.3 u
= 14.3 x 10
= 143
Answer(s): 143
