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 formula required to solve this problem O A IPrt, where I ls the Interest, P is the principal, is the annual simple interest rate and tin the time in years OB. AP(1 + r), where A is the amount, P is the principal, in the annual simple interest rate, and is the time in years C. A=P(1+1)", where and Als the amount at the end of a periods, P is the principal value, r in the annual nominal rate, mis number of compounding periods per year, i la rate per compounding period, and n is total number of compounding periods OD. Ape" where is the amount at the end of t years it Pis 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.)
