You are considering purchasing a new car and you want to do some financial research first. a) Determine the best interest rate for a new car purchase for a 48- month loan at a bank near you. If you finance a $25,999 with such a loan, determine the monthly payment and the total interest paid over the course of the loan. b) Determine the best interest rate for a new car purchase for a 48- month loan at a credit union near year. Determine the monthly payment and the total interest paid if the same auto loan is financed through the credit union. c) Is it true that the credit union would save you money? The formula is called "Amortization Payments" and can be found on page 257 of the text. A loan of P dollars at interest rate i per period may be amortized in n equal periodic payments of R dollars made at the end of each period, where R = Pi 1- (1 + i)-n Note that i = r/12 which is the monthly interest rate.
