Three weekly parking fees are $26, $34, and $18. What is the average for these three weeks?

• A. 24
• B. 26
• C. 28
• D. 30

Answer: (B)

Finding the average means adding all the values and then dividing by how many values you have. Here, add the three weekly amounts: 26 plus 34 equals 60, and 60 plus 18 equals 78. There are three weeks, so divide 78 by 3 to get 26. That makes 26 the average weekly parking fee. The other numbers would require the total to be 72, 84, or 90, which doesn’t match the actual total of 78, so they aren’t correct.
