14. a car worth $27,500 in 2012 is worth $16,720 in 2016. find the rate of change in the value of the car.
Answer
Explanation:
Step1: Identify change in value and time
Change in value: ( 16720 - 27500 = -10780 ) Time change: ( 2016 - 2012 = 4 ) years
Step2: Calculate rate of change
Rate of change = ( \frac{\text{Change in Value}}{\text{Change in Time}} = \frac{-10780}{4} = -2695 )
Answer:
The rate of change in the value of the car is (-$2695) per year.
