Automobiles usually depreciate in value over time. Often a newer automobile may be worth only 80% of its previous year's value. Suppose that a car is worth $25,000 new.
(a) How much is it worth after 1 year? After 2 years?
(b) Write a formula for a sequence that gives the car's value after n years.
(c) Make a table that shows how much the car was worth each year during the first 7 years.
