An investor wants to invest $30,000 in corporate bonds that are rated AAA, A, and B. The lower rated ones pay higher interest, but pose a higher risk as well. The average yield is 5% on AAA bonds, 6% on A bonds, and 10% on B bonds. Being conservative, the investor wants to have 5. twice as much in AAA bonds as in the B bonds. How much should she invest in each type of bond to have an interest income of $2000?
