Solve the problem.Alan wants to invest a total of $11,000 in mutual funds, CDs, and a high yield savings account. He wants to invest no more in mutual funds than half the amount he invests in CDs. He also wants the amount in savings to be at least twice the sum of his CDs and mutual funds. His expected return on mutual funds is 10%, on the CDs is 6%, and on savings is 3%. How much money should Alan invest in each area in order to have the largest return on his investments? Set this up as a linear programming problem in the following form: Maximize cTx subject to Ax ? b and x ? 0. Do not find the solution.
A. Let x1 be the amount invested in mutual funds, x2 the amount in CDs, and x3 the amount in savings.
Then b =
