If you borrow L dollars for N years at a yearly interest rate r, your monthly payment

Question:

If you borrow L dollars for N years at a yearly interest rate r, your monthly payment of P dollars is calculated using the equation

1-6-12N 6-1 L=P  where b = 1 + r 12

(a) Find P if L = $5000, N = 3, and r = 0.08 (8%).
(b) You are offered a loan of L = $5000 to be paid back over 3 years with monthly payments of P = $200. Use Newton’s Method to compute b and find the implied interest rate r of this loan.

(L/P)b2N+1(1+ L/P)b2N + 1 = 0
