Question 112391: Joe's Used Cars sold 50 Cars in 2002. In 2007, they sold 180 cars. Find the average rate of change in cars sold from 2002 to 2007.
- I guessed that this was a proportion. I subtracted the years to get 5, then I crossed multiplied to get an answer of 18. although I am not sure if that is correct. Answer by checkley71(8403) (Show Source):

130/5=26 IS THE AVERAGE INCREASE IN SALES EACH YEAR BETWEEN 2002 & 2007.
