What is the mean number of movie tickets sold during the week?
A. 17
B. 21
C. 18
D. 16

Answer 1

A. 17

Explanation:

The "mean" is the same as an average.

To find the mean, add all the numbers.

Then divide that sum by the total numbers you added.

18+23+9+16+30+16+7=119.

119/7= 17. (We divided by 7 because we added 7 numbers)

Hope this helps!
