Final answer:
The mean price of a cheese pizza from the prices listed is calculated by summing up all the prices and dividing by the total count. The sum is $42, and when divided by 7, the result is a mean price of $6.
Step-by-step explanation:
To find the mean price of a cheese pizza from the given prices of $5, $5, $4, $6, $6, $8, and $8, we first add all the prices together and then divide by the number of prices to calculate the mean.
Sum of prices = $5 + $5 + $4 + $6 + $6 + $8 + $8 = $42
Number of prices = 7
Mean price = Sum of prices ÷ Number of prices = $42 ÷ 7 = $6
Therefore, the mean price of a cheese pizza is $6.
