Enter your answer es a percent rounded to 2 declmal places, e.g. 32.16.) a. Monthly payment b. Effective annual rateExplanation / Answer
a)
Rate = 0.057 / 12 = 0.00475 or 0.475%
Present value of monthly payments = Monthly payments * [ 1 - 1 / ( 1 + r)n] / r
75,500 = Monthly payments * [ 1 - 1 / ( 1 + 0.00475)60] / 0.00475
75,500 = Monthly payments * 52.100665
Monthly payments = $1,449.12
b)
Effective interest rate = ( 1 + APR/n)n - 1
Effective interest rate = ( 1 + 0.057/12)12 - 1
Effective interest rate = 0.0585 or 5.85%
