Bart Simpson, age 9, wants to be able to buy a really cool new car when he turns 15. His really cool car costs $17,000 today, and its cost is expected to increase 4 percent annually. Bart wants to make one deposit today (he can sell his mint-condition original Nuclear Boy comic book) into an account paying 8.3 percent annually in order to buy his car in 6 years. How much will Bart's car cost, and how much does Bart have to save today in order to buy this car at age 15?
