10 people attended class on Monday, 15 on Tuesday, and 10 on each day from Wednesday through Friday. What was the average number of people who attended class each day?
A total of 10 + 15 + 10 + 10 + 10 = <<10+15+10+10+10=55>>55 people attended class across the 5 days
An average of 55 people / 5 days = <<55/5=11>>11 people per day attended class
