An investor has $12,000 to invest into two different funds. fund a, which is a high risk fund, yields an average return of 14%. fund b, which is a low risk fund, yields an average return of 6%. to reduce the risk, the investor wants the amount in fund b to be at least twice the amount in fund a. how much should be invested in each fund to maximize the return?

By computing let be the variable X be the amount of Fund A and variable Y be the amount of Fund B.So fund b should be at least twice the amount of fund A it means that X =X +2Y and Y is still the same. So to calculate X+Y = 12000, first count all the variables present in the equation, its 4 so divide 12,000 to 4 you will come up with 3000. That is the value of A = 3000, the B is 3,000 plus twice the vale of A so the value of B is 9,000
