First you need to understand that this question is simply following mean, median, and mode. You need to arrange the numbers from least to greatest. That means your numbers are as follows: 653, 698, 764, 845, 923. To find the yearly average of customers, you add those numbers up and you get 3,883. You then divide 3,883 by 5 and you get 776.6 as your answer. So your yearly average of customers is 776.6.
Hope this helps.
