Answer:
A mean in math is when you have a set of numbers, you add up all numbers of the set and then divide that sum by the total amount of numbers.
Example: 3,6,8,9
3+6+8+9=26
26/4 (because there is four numbers)
26/4= 6.5
So the mean of that set will be 6.5
Step-by-step explanation:
The answer is $26.00 because
$6.50*(4+1)= $6.50*5, which is $26.00.
