## Introduction

I have a \$100,000 annual salary, and have decided to spend it on the 2015 Ford Fusion. This car will cost a total of \$25,000 before interest. After interest, the car will cost a total of blank. The rest of my income will be spent on paying for my house, taxes, food, medical insurance, financial savings, as well as anything else I may need.

## Extra Credit Problem

Mrs. O’Connell wants to buy a new car that costs \$24,516.00. The car dealership is offering 0% interest for a 5 year loan. They also offer a \$4,000 rebate instead of 0% financing with 3.75% interest. Help Mrs. O’Connell determine which is the better deal? Show work and justify your answer.

\$4,000 Rebate

20,516=R(1-(1+.0375/12)^-12(5)/.0375/12)

1+(.0375/12)=1.00312

1.00312^-12(5)=.82951

1-.82951=.17048

.17048/(.0375/12)=54.55360

20,516=54.55360R

20,516/54.55360R=376.07050

\$376.07 Per Month

0% Interest

24,516=R(1-(1+0/12)^-12(5)/0/12

24,516^12(5)=408.6

\$408.60 Per Month

## Extra Credit Explanation

Mrs. O'Connell would be wise to take the \$4,000 rebate over the 0% financing. With the rebate, Mrs. O'Connell will pay \$376.07 a month as opposed to paying \$408.60 a month with the 0% interest. Over the next 5 years, she will save \$32.53 each month by taking the rebate deal over the no interest deal. By taking the rebate deal, Mrs. O'Connell will save a grand total of \$1,951.80 over the next five years.
