Solve the problem using graphical approximation techniques on a graphing calculator. How long does it take for a $2,600 investment at 12% compounded quarterly to be worth more than a $3,100 investment at 7% compounded quarterly? Identify the formule required to solve this problem O A 1a Prt, were is the interest. Pis the principal, r is the annual simple interest rate, and t is the time in years OB. AP11 1), where is the amount, P is the principal, r is the annual simple interest rate, and t is the time in years A=P(1 19", where and A is the amount at the end of n periods, Pis the principal value, r in the annual nominal rato, mie number of compounding periods per year, ils rato per compounding period, and n in total number of compounding periods OD. A Pet, where is the amount at the end of t years if P is the principal invested at an annual rater compounded continuously It will take quarters for a $2,600 investment at 12% compounded quarterly to be worth more than a $3,100 investment at 7% compounded quarterly. (Round up to the nearest Integer.) C
