If you borrow L dollars at an annual interest rate of r (in decimal form, so 5% is written as 0.05, for a period of m years, then the size of the monthly payment, M, is given by the annuity equation 12M L = -[1-(1 + r/12) 12m Suppose you need to borrow $150,000 to buy the new house that you want, and you can only afford to pay $600 per month. Assuming a 30-year mortgage, use the bisection method to determine what interest rate you can afford to pay. (Should you perhaps find some rich relatives to help you out here?)
