The graph below shows the number of cars a company sold each year throughout a five year period. If in the first year the company sold 15 cars,what is the average number of cars the company sold over the five-year period?
If they sold 15 cars each year, the average will be 15 since its no more or no less, it stays the same and they sell the SAME amount every year, 15 once, 15 again, 15 again, and so on. That makes the average 15.
