The value of a brand new car is $10,000 and the value depreciates 18% every year. Write a function to represent the value of the car after t years, where the quarterly rate of change can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per quarter, to the nearest hundredth of a percent.

delivery truck is purchased new for $54,000.

a. Write a linear function of the form y = mt + b to represent the value y of the vehicle t years after purchase. Assume that the vehicle is depreciated by $ 6750 per year.

y = Vobty=Vobt V0V0

c. To the nearest dollar, determine the value of the vehicle after 4 yr and after 8 yr using the linear model.

d. To the nearest dollar, determine the value of the vehicle after 4 yr and after 8 yr using the exponential model
