Solve the problem using graphical approximation techniques on a graphing calculator. How long does it take for a $2,400 investment at 12% compounded quarterly to be worth more than a $3,000 investment at 5% compounded quarterly? Identify the formula required to solve this problem. O A. A= P(1 + rt), where A is the amount, P is the principal, r is the annual simple interest rate, and t is the time in years O B. A= P(1 + i)", where i = -, and A is the amount at the end of n periods, P is the principal value, r is the annual nominal rate, m is number of compounding periods per year, i is rate per compounding period, and n is m total number of compounding periods O C. A=Pert, where A is the amount at the end of t years if P is the principal invested at an annual rate r compounded continuously O D. I = Prt, where I is the interest, P is the principal, r is the annual simple interest rate, and t is the time in years
