HELP WITH PLOTTING GRAPH diversification to the extent that at least $40\%$ of the investment be placed in Treasury notes. It is also decided that no more than $30\%$ of the investment be placed in bonds.

The aim of the objective function for Rio Credit Union should be to Maximize the objective value.

Decision variables:

$x=$$ invested in Treasury notes

$Y=$$ invested in Bonds

Objective function $($in decimals, eg$.,07,$ NOT $7\%)$:

$Z=$ROI$=\mathrm{.}10x+\mathrm{.}09Y$

Subject to:

$1x+1Y,=$$$250,000(C_1)$

$1x+0Y,$$$100,000(C_2)$

$0x+1Y,$$$75,000(C_3)$

$x,Y0,$

On the graph on right, constraints $C_1,C_2$ and $C_3$ have been plotted using the line plotting tool.

Using the point drawing tool, plot all the corner points for the feasible area.
