A car dealer sells a new car for $18,000. He also offers to sell the same car for payments of $375 per month for five years. What monthly interest rate is this dealer charging? To solve this problem you will need to use the formula for the present value A of an annuity consisting of n equal payments of size R with interest rate i per time period: R A = 1 - (1 + i)*] Replacing i by x, show that 48x(1 + x)60 – (1 + x)0 + 1 = 0 Use Newton's method to solve this equation.
