Question

Over the last 5 days, you made the following numbers of sales calls: 8, 7, 9, 5, and 7. On the average, how many sales did you make each day? *

Answer 1

7 sales

Step-by-step explanation

We are given that over 5 days, the number of sales made are:

8, 7, 9, 5 and 7

To find the average sales made per day, we have to add up all the sales made over the 5 days and then divide by the number of days (5):

`\begin{gathered} \text{Average Sales = }\frac{Sum\text{ of all sales}}{number\text{ of days}} \\ \text{Average Sales = }\frac{8\text{ + 7 + 9 + 5 + 7}}{5}\text{ = }(36)/(5) \\ \text{Average Sales = 7.2 }\cong7\text{ sales} \end{gathered}`

An average of 7 sales were made per day.
