Question

An assembly line produced 23 units on Monday, 15 units on Tuesday, 20 units on Wednesday, 18 units on Thursday and 9 units on Friday What was the average production for the line for the week?

Answer 1

To find the average in this problem you would add the number of units for each day and divide by the number of days (units/days) so the answer is 17

Answer 2

The answer is 17; you add the numbers, and divide by the number of days.  The numbers add up to 85; you divide 85 by 5 (days) to get 17.
