Question
What is the mean amount spent on lunch?
Answer options with 4 options
A.
$8.50
B.
$10.00
C.
$10.25
D.
$11.25
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
