Mr. Stevenson wants to purchase a new hat. The table below shows the prices of various hats. What is the difference, in dollars, between the mean price and the median price of a hat from the list?

Answer:

39 - 35 = $4

mean: 19+42+35+40+39 = 175

            175/5 = 35

add up all the cost then divide by how many numbers there are.

Median:

list the numbers from lowest to largest

19, 35, 39, 40, 42

then find the number in middle

39

last: 39-35=$4
