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
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.
