A financial advisor is about to build an investment portfolio for a client who has $100000 to invest. The four investments available are A,B,C, and D. Investment A will earn 4 percent and has risk of two “points” per $ 1000 invested. B earns 6 percent with 3 risk points; C earns 9 percent with 7 risk points; and D earns 11 percent with a risk of 8. The client has put the following conditions on the investments: A is to be no more than onehalf of the total invested. A cannot be less than 20 percent of the total investment. D cannot be less than C. Total risk points must be at or below 1,000. Determine the amount of each investment that should be purchased.
Note : Focus on the unit of measure that you use for the investments.
