Cars in high demand that are also in low supply tend to retain their value better than other cars. The data in the table is for a car that won a resale value award. Year : value(%)
1 : 84
3 : 64
5 : 44
a. Write a function to represent the change in the percentage of the car's value over time. Assume that the function is linear for the first 5 years.
b. According to the model, by what percent did the car's value drop the day it was purchased and driven off the lot?
c. Would the linear model be useful after 10 years? Explain why or why not.
d. Suppose months were used instead of years to write the function. How would the model change? What's the relationship of the new function to the
original function?

I can’t for the life of me figure this out please help me
