Sally invests some money at 6%/a compounded annually. After 5 years, she takes the principal and interest and reinvests it all at a 7.2%/a compounded quarterly for 6 more years. At the end of this time, her investment is worth 14,784.56.how much did sally originally invest?
I tried solving this and got 7276.81. am i correct?
