Accepted Solution

A:

counter claim :

50% of 100 > 75% of 50...

0.5(100) > 0.75(50)

50 > 37.5

supporting claim :

50% of 25 < 75% of 30

0.5(25) < 0.75(30)

12.5 < 22.5

50% of 100 > 75% of 50...

0.5(100) > 0.75(50)

50 > 37.5

supporting claim :

50% of 25 < 75% of 30

0.5(25) < 0.75(30)

12.5 < 22.5
