A random survey found that 6 of the 20 people surveyed prefer listening to rock music. Based on those results, about how many

people prefer listening to rock music from a population of 100 people?

A. 18

B. 24

C. 48

D. 30

30%

Convert fraction (ratio) 6 / 20 Answer: 30%

Step-by-step explanation:

The strategy here is to see how many times the "percent number" (in this case, 25) goes into 100, and then count by that number until we reach 100-the whole thing.

D. 30

Step-by-step explanation:

6/20 = x/100

600 = 20x

600/20 = x

x = 30
