This is a four part project where students explore buying various vehicles and calculating the interest they would pay on their loans. The project comes with 3 Car Sales Ad's. Part one of the project students look at the first two ads and pick one car from each ad. They will calculate sales tax, the total price, the simple interest accrued over five years and what the monthly payment will be. The second part the students calculate the fuel efficiency of each car by using the MPG to calculate the cost of gas weekly and monthly. Part three students will choose which car they would buy and explain why. In part four there is a third ad with three expensive sport cars. The students will again calculate the simple interest as well as the monthly payments after a 20% down payment. This is a great project to gain practice and understanding of simple interest.
