this is the problem number 18 in week 4 forum Math 110 American Military University.

there are total 30 problems in which a student has to choose 1 problem and post the solution.

This is a moderated forum. Your posting will not be visible to the rest of the class until I approve it. Occasionally, more than one person will tackle a problem before they can see the work of others. In that case, credit will be given to all posters. Once the solution to a problem has become visible, that problem is off limits and you will need to choose a different problem in order to get credit.

18) A retired couple has $160,000 to invest to obtain annual income. They

want some of it invested in safe Certificates of Deposit yielding 6%. The

rest they want to invest in AA bonds yielding 11% per year. How much

should they invest in each to realize exactly $15,600 per year?
