1. Make a line graph of the sales data.
2. Calculate the average daily sales for this period.



Answer :

### Line Graph

To create a line graph, follow these steps:

1. Label the X-axis and Y-axis.
- X-axis represents the days of the week: Monday through Friday.
- Y-axis represents the sales (in thousands of dollars).

2. Plot the Sales Data.
- For Monday (Mon), the sales are 125 thousand dollars.
- For Tuesday (Tue), the sales are 114 thousand dollars.
- For Wednesday (Wed), the sales are 118 thousand dollars.
- For Thursday (Thu), the sales are 130 thousand dollars.
- For Friday (Fri), the sales are 158 thousand dollars.

3. Connect the Dots.
- Plot each point and draw lines to connect them sequentially from Monday to Friday.

Your graph should look something like this:

```

### Calculating the Average Daily Sales

1. List the Sales Amounts:
- Monday: 125 thousand dollars
- Tuesday: 114 thousand dollars
- Wednesday: 118 thousand dollars
- Thursday: 130 thousand dollars
- Friday: 158 thousand dollars

2. Sum the Sales Amounts:
[tex]\[ 125 + 114 + 118 + 130 + 158 = 645 \][/tex]

3. Count the Number of Days:
[tex]\[ 5 \text{ days} \][/tex]

4. Calculate the Average:
[tex]\[ \text{Average sales} = \frac{\text{Total Sales}}{\text{Number of Days}} = \frac{645}{5} = 129 \][/tex]

### Final Answer:
The average daily sales from Monday to Friday is 129 thousand dollars.
