# Math 132 1019 – 2021 Fall Sec

I need your help specifically on part B,C, and D

I think for B it could be A=(6000,2000) B=(8000,2000) C=(6000,4000) or or or the one below.

I think C can be (6000,2000) or (1500,500) or the one below.

I think D can be $880 or$940 or the one below

A woman has up to $10000 $10000$ to invest. Her broker suggests investing in two bonds: Bond A $A$ , and Bond B. $B.$ Bond A $A$ is a rather risky bond with an annual yield of 10% $10%$ and bond B $B$ is a rather safe bond with an annual yield of 7% $7%$ . After some consideration, she decides to invest at most$6000

$6000$

in bond A

$A$

, and invest at least \$2000

$2000$

in bond B.

$B.$

Moreover, she wants to invest at least as much in bond A

$A$

as in bond B.

$B.$

She wishes to maximize her annual yield.

on the y-axis) to determine the coordinates of the corner points of the solution region. Then, select the answer from this list:

c) Which of the feasible corner points you selected in part (b) above maximizes the objective function? Note that a feasible corner point is any corner point with at least one non-zero coordinate. Select the answer from this list:

d) What is the maximum yield?
