Question

A small deli is open 2 hours during lunch. The number of customers they served on the five weekdays, Monday through Friday, this week are 158, 170, 164, 121, and 192. What is the average number of customers served during lunchtime?

Answer 1

To find the average number of customers served during lunchtime over the five weekdays, you first need to sum the number of customers served each day and then divide that sum by the total number of days.

The number of customers served on each day is as follows:
- Monday: 158
- Tuesday: 170
- Wednesday: 164
- Thursday: 121
- Friday: 192

Let's calculate the total number of customers served:

\[
158 + 170 + 164 + 121 + 192
\]

Calculating step by step:
- \(158 + 170 = 328\)
- \(328 + 164 = 492\)
- \(492 + 121 = 613\)
- \(613 + 192 = 805\)

Now, the total number of customers served during the week is \(805\).

Next, we divide this total by the number of days (5) to find the average:

\[
\text{Average} = \frac{\text{Total customers}}{\text{Number of days}} = \frac{805}{5}
\]

Calculating the average:

\[
\frac{805}{5} = 161
\]

Therefore, the average number of customers served during lunchtime is \(\boxed{161}\).
