Javier entered college in the fall semester and was awarded financial aid.  He did not receive any academic scholarships.  On his first day of class, Javier was told the books required for each class and his book cost would be $850.00 for the first semester.  He was shocked and did not have the money for books.  He did not know that many times when students are awarded financial aid, they receive an over payment check.  Javier received his over payment check of $4000.  Javier had never seen $4000 and he wanted a car.  Javier went to a used car lot and was able to purchase a car.  He knew nothing about interest rates, annual percentage rates, car insurance and what it would take to maintain his used 2014 vehicle.

Did Javier make a good decision?  Explain your answer.
