Question

Lauren bought supplies for a class project and brought the receipt to school. The 8 items cost:
$8.00$9.00$8.00$8.00$9.00$7.00$9.00$6.00
What was the mean price of the items?

Answer 1

To find the mean price of the items, we first need to calculate the total cost of all the items and then divide that by the number of items.

The costs of the items are:
- $8.00
- $9.00
- $8.00
- $8.00
- $9.00
- $7.00
- $9.00
- $6.00

Now we will add these amounts together:

\[
8.00 + 9.00 + 8.00 + 8.00 + 9.00 + 7.00 + 9.00 + 6.00
\]

Calculating step-by-step:

\[
8.00 + 9.00 = 17.00
\]
\[
17.00 + 8.00 = 25.00
\]
\[
25.00 + 8.00 = 33.00
\]
\[
33.00 + 9.00 = 42.00
\]
\[
42.00 + 7.00 = 49.00
\]
\[
49.00 + 9.00 = 58.00
\]
\[
58.00 + 6.00 = 64.00
\]

So, the total cost of the items is $64.00.

Next, we count the number of items, which is 8.

To find the mean, we divide the total cost by the number of items:

\[
\text{Mean} = \frac{\text{Total Cost}}{\text{Number of Items}} = \frac{64.00}{8} = 8.00
\]

Thus, the mean price of the items is \(\boxed{8.00}\).
