### Mean:

7.75, Mode: $10.50

Answer 2

## Step 1: Calculate the Total Cost### We are given the costs of the 8 DVDs Gabriel bought. Three cost

7.75 each, one costs

3.50 each. To find the total cost, we multiply the number of DVDs by their respective prices and sum the results:

10.50) + (2 \times \

5.25) + (2 \times \

31.50 + \

5.25 + \

59.25

= \frac{\text{Total Cost}}{\text{Number of DVDs}} = \frac{\

7.40625 \approx \

.## Step 3: Calculate the Median### To find the median, we first arrange the DVD prices in ascending order:

. Since there are 8 DVDs (an even number), the median is the average of the 4th and 5th values. Median

7.75 + \

7.75

10.50 appears three times, which is more frequent than any other price. Therefore, the mode is $10.50.
