An investment of $500 earns interest at an annual interest rate of 13%. The equation for this investment is B = 500(1.13)t, wher
e B represents the balance and t is the number of years. Write an equivalent equation that displays the effective monthly interest rate. A) B = 500(1.10)12t B) B = 500(1.12)12t C) B = 500(1.010)12t D) B = 500(1.012)12t
