Question

Xavier bought a new car for $33,000 in the year 2008. He knows that the value of the car has depreciated linearly. If the value of the car in 2011 was $16,500 , what was the annual rate of change of the car's value? Round your answer to the nearest hundredth if necessary.

Answer 1

50%

0.5

1/2

because 16,500 is half of 33,000

16,500÷33,000=0.5

take 16,500 and divide it by 33,000 to get the rate of change
