Dominic bought supplies for a class project and brought the receipt to school. The 8 items cost:

Question

$4.00$3.00$6.00$7.00$4.00$3.00$2.00$7.00
What was the mean price of the items? Round your answer to the nearest whole number.

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 by the number of items.

The costs of the 8 items are as follows:

• $4.00
• $3.00
• $6.00
• $7.00
• $4.00
• $3.00
• $2.00
• $7.00

Now, let's sum these amounts:

\[ 4.00 + 3.00 + 6.00 + 7.00 + 4.00 + 3.00 + 2.00 + 7.00 \]

Calculating step by step:

• \(4.00 + 3.00 = 7.00\)
• \(7.00 + 6.00 = 13.00\)
• \(13.00 + 7.00 = 20.00\)
• \(20.00 + 4.00 = 24.00\)
• \(24.00 + 3.00 = 27.00\)
• \(27.00 + 2.00 = 29.00\)
• \(29.00 + 7.00 = 36.00\)

The total cost of the items is \(36.00\).

Next, we find the mean by dividing the total cost by the number of items:

\[ \text{Mean} = \frac{\text{Total Cost}}{\text{Number of Items}} = \frac{36.00}{8} = 4.50 \]

Finally, rounding this to the nearest whole number gives us:

\[ \text{Mean Price} \approx 5 \]

Thus, the mean price of the items is \(\boxed{5}\).
