Marco is trying to decide between several different vehicles and loan structures. His primary goal is to reduce his payment as much as possible. He has the following options to consider:

A car that costs $12,000 that the bank will give him a loan at 5.5% for 6 years.

A car that costs $12,500 that the bank will give him a loan at 6.0% for 6.75 years.

A car that costs $13,000 that the bank will give him a loan for 4.5% for 5 years.

So, which loan should he choose?

b.) Marco has $1,000 per month in his budget over his monthly expenses. After paying for his new car loan, he wants to invest the difference every month (so $1,000 his car payment amount). Assuming he earns 10%, compounded monthly, and assuming he continues investing for 10 years at the same monthly amount (even after his car is paid for), how much money will he have at the end of 10 years?

c.) After five years of investing, Marco is so excited by the results of his account that he decides to add $5,000 from his savings account to his investment account. He also earns 10%, compounded annually, on this money. How much additional money does he have after five years of investing this amount?
