To find the mean (average) amount spent on lunch, we need to add up all the amounts spent and then divide by the number of people.
$12.00 + $8.00 + $11.25 + $7.75 + $9.25 + $11.25 + $10.75 + $9.75 = $80.00
Now, divide $80.00 by 8 (the number of people):
$80.00 / 8 = $10.00
So, the mean amount spent on lunch is $10.00.
Therefore, the correct answer is option B. $10.00
A group of 8 people went out to lunch. The amount each spent is shown in the table.
