| Before |
11 u |
5 u |
10 u |
| Change |
+ 0.5 u |
+ 2 u |
- 2.5 u |
| After |
11.5 u |
7 u |
7.5 u |
Number of buttons that Clint gave to Wesley and David
=
14 x 10 u
= 2.5 u
Number of buttons that David received from Clint
=
40100 x 5 u
= 2 u
Number of buttons that Wesley received from Clint
= 2.5 u - 2 u
= 0.5 u
Number of less buttons that Clint had less than Wesley
= 11.5 u - 7.5 u
= 4 u
4 u = 80
1 u = 80 ÷ 4 = 20
Number of buttons that Wesley and Clint had
= 11.5 u + 7.5 u
= 19 u
= 19 x 20
= 380
Answer(s): 380
