To Find Percent Error

When consumers buy a car, they are faced with a dizzying array of choices, from options to models to colors. Then, when they finally arrive at a decision for all these items, and the total price is computed, they need to find a way to pay for the car.

At this point, the car salesman will likely refer the customer to the financing department, where a large number of options will be presented. Due to the high price of a new vehicle, many consumers require financing to buy transportation.

If a customer can pay cash for the car, they need to decide if that is the best option for them. They must trade off the use of the cash versus the amount they will save on interest over the period of the loan.
