In 2003, Chris bought a new car for $30,500. The car was worth $22,000 in the year 2010. If Chris knows that the value of the car depreciated linearly, what was the annual rate of change of the car's value? Round your answer to the nearest hundredth if necessary.

Well you can start by dividing 20 by 2 because that would give you the half that you finished in class 24 divided by 2 =12 if you finish four more you wound have 12-4=8 you have 8 problems left and now you have to find the fraction so start with 8/24 and then simplify your answers would be 1/3
