One eighth of the class graduated with an A average, 1/2 got a B, and the rest of the class had a C average. In a class of 800, how many had a c average
Accepted Solution
A:
1/8 of the class graduated with an A average 1/2= 4/8 got a B the rest of the class had a C average = 3/8
In a class of 800
800/8 = 100
so
1/8 of the class graduated with an A average = 100 1/2 got a B = 400 the rest of the class had a C average = 300
