Suppose we divide a group of 100 drivers into three groups. In a given year, 40 of those people have only a few door dings or chipped paint, which costs $300 each. Another 40 of the drivers have medium-sized accidents that cost an average of $1,500 in damages, and 20 of the drivers have large accidents that cost $12,000 in damages. What will the total damage incurred by car accidents in this group of 100 drivers be?
