3. Assume that a one-year CD purchased for $2000 paysan APR of 12% that is compounded quarterly. How much is in theaccount at the end of each compounding period? (Calculate theinterest and compound it each period rather than using the compoundinterest formula. Round your answers to the nearest cent.)first quarter $ second quarter $ third quarter $ fourth quarter $ How much total interest does it earn? (Round your answer to thenearest cent.)$ What is the APY? (Round your answer to two decimal places.) %
An inheritance of $40,000 was divided among three investmentsyielding $3,500 in interest per year. The interest rates for thethree investments were 7%, 9%, and 11%. Find he amount places ineach investment if the amount was invested at 9% was $3,000 lessthan the amount was invested at 7%.a. Define the 3 by 3 system of equations for this problem.b. Solve the system of equations to find the amount placed ineach investment.
