To find the average number of locations chosen per potential customer, we need to know two amounts: the total number of potential customers surveyed and the total amount of times all the locations were chosen by those potential customers surveyed. The first amount is 40, according to the information provided. For finding the second amount, we should use the following formula:
Total of times locations were chosen = times that grocery stores were chosen + times that drugstores were chosen + times that health food stores were chosen + times that big box stores were chosen
Total of times locations were chosen = 20 + 14 + 10 + 16
Total of times locations were chosen = 60
Now, for finding the average, we take the total of times location were chosen and divide it by the number of potential customers surveyed
Average = 60 / 40
Average = 1.5
The correct answer is C. 1.5
