Linear Programming Word Problem Dr. Lum teaches part-time at two different community colleges, Hilltop College and Serra College. Dr. Lum can teach up to 7 classes per semester. For every class taught by him at Hilltop College, he needs to spend 3 hours per week preparing lessons and grading papers, and for each class at Serra College, he must do 4 hours of work per week. He has determined that he cannot spend more than 24 hours per week preparing lessons and grading papers. If he earns
$4,200
per class at Hillop College and
$4,600
per class at Serra College, how many should he teach at each college to maximize his income, and what will be' his income? a. Letting
x
be the first of the variables listed in the problem statement, and
y
the second, write the objective function.
z=
?
b. Graph the feasible region on paper, then list the corner points of the feasible region. (Enter ordered pairs (
x,y
), separated by commas.) c. Test the corner points to find the optimum value of the objective function: The "winning" corner point is
?
The optimum value of the objective function is
?
