Question 1086843: Find the maximum of the objective function, f, subject to the constraints f=15x +25y {3x +4y > 60
x + 8y > 40
11x + 28y < 380
x>0, y>0
The greater and less than signs have the or equal to underscore. If possible could you show me the steps in detail because I am confused beyond belief.

First graph each inequality.

Then overlay them to define the feasible region,
.
.
.

.
Take out the inequality and just graph the boundary lines to make it more visually appealing and understandable.
.
.
.
.
.
.
Find the vertices using the intersection of the boundary lines.
.
.
Test the objective function at each of the vertices to find the maximum value,
I'll do one.
You do the others the same way.
(4,12):f=15%284%29%2B25%2812%29=60%2B300=360
Do the other two vertices the same way and see what the max value is and where it occurs.
