Quizplus · Accepted Answer

If 4 out of 10 adults buy their drugs at large drug stores, that means the proportion is 4/10 or 0.4. To find out how many of the 34,000 adults buy their drugs at large drug stores, we can multiply:
0.4 x 34,000 = 13,600
Therefore, we can expect 13,600 adults to buy their drugs at large drug stores. To find the number of adults who would buy their drugs at large drug stores, we need to multiply the total number of adults in the city by the fraction who buy their drugs at large drug stores:
 (4/10) x 34,000 = 13,600 adults. Therefore, the answer is C.
