<prompt> Human: I have 9,000 that I want to use to pay down some student loans. My goal is to minimize the overall interest incurred. For the sake of the exercise, lets assume that Im going to be paying the minimum monthly payment on each going forward. How do I best allocate the money?Loan 1Balance: 1,897.26Periods: 120Rate 7.9Payment 247.53Loan 2Balance: 5,441Periods: 120Rate 7.9Payment 172.62Loan 3Balance: 8,444.51Periods: 120Rate 6.8Payment 157.21  <response>: No need to calculate anything. Pay off 1 and 2 that have the highest interest rate, and put the rest toward 3. Lucky you, this is both the most emotionally appealing approach and the cheapest. Not that the difference between 6.8 and 7.9 matters that much here.
