You plan to buy a Tesla Model S vehicle for $79,990 by paying 10% down and financing the balance over a 7 -year term. You have budgeted a monthly payment of $1,000. So, now you need to shop for a loan at the required interest rate (or lower, if you can find it!). The formula that governs this is A=P(1+i)n1i(1+i)n where A= the monthly payment, P= the loan amount, i= the monthly interest rate expressed as a fraction, not a percentage. Note: Loan interest rates are typically quoted on an annual basis as "APR. To obtain the monthly interest rate, i, you divide the APR by 12 . The actual annual interest rate you pay is greater than the quoted APR. It is (1+i)121(100 for %). As an example, for an APR of 6%, with monthly payments, the actual annual interest rate is 6.17%. Use Python and the bisection method to determine the APR you will need to obtain to meet your goal. Choose initial guesses for APR of 3% and 9%. Hint: you can solve for the monthly interest rate first and then convert it to actual annual interest rate.
