Question 1075426: Could you please help me solve this word problem?
Congratulations! You have just been hired as a manager of Todaro�s, a small
business that makes frozen pizzas to sell at local markets. The owner gave
you the following information:

-
Preparation and packaging takes 0.2 hours for each box of 12-inch pizzas
and 0.25 hours for each box of 16-inch pizzas.

-
You can pay the staff for no more than 240 hours of labor each week.

-
The staff must meet the company quota of producing at least 1,000 boxes
of pizza per week.

-
Todaro�s will make a profit of $2 for each box of 12-inch pizzas and $4
for each box of 16-inch pizzas. How many pizzas of each size must be
produced in order to maximize the profit? (15 pts.)

Let x represent the number of 12-inch pizzas made and let y represent
the number of 16-inch pizzas made.

a. Write an inequality for each constraint. (Hint: There are 4.)

b. Graph the feasible region that represents the constraints in
(a). (Note, you must submit a graph to earn full credit.)

c. Locate and label the vertices for the feasible region.

d. Write the objective function.

e. Find the number of each type of pizza made that will maximize
Todaro�s profit.
thanks!
