I believe the question should read
The amount of an investment is $16760.87 and the rate is 9.5% per year, compounded monthly, for 6 years . What is the principal and compound interest?
The amount of an investment is $16760.87 and the rate is 9.5% per year, compounded monthly, for 6 years . What is the principal and compound interest?
16760.87 = P(1+.095/12)6×12 so that the invested principal P is 16760.87/(1+.095/12)72 =9499.996=9500.00
The interest earned is 16760.87-9500=7260.87
