A television manufacture makes rear – projection and plasma televisions. The profit per unit is $ 125 for the rear–projection televisions and $ 200 for the plasma televisions.
a. Let x = the number of rear – projection televisions manufactured in a month and y = the number of plasma televisions manufactured in a month. Write the objective function that models the total monthly profit.
The manufacture is bound by the following constraints:
Equipment in the factory allows for making at most 450 rears – projection televisions in one month.
Equipment in the factory allows for making at most 200 plasma televisions in one month.
The cost to the manufacturer per units is $600 for the rear–projection and $900 for the plasma televisions. Total monthly costs cannot exceed $360,000,
Write a system of three inequalities that models these constraints.
c. Graph the system of inequalities in part (b). Use only the first quadrant and its boundary
because x and y must both nonnegative
d. Evolutes the objective function for the total monthly profit at each of the five vertices of the graphed region. [The vertices should occur at (0.0), (0.200), (300,200), (450, 100), and (450.0).]
e. Complete the missing portions of this statement: The television manufacture will make the greatest profit by manufacturing ______ rear–projection television each month and _____ plasma television each month. The maximum monthly profit is $ __________.

- Use your schools library, the Internet, or some other reference source to find the real-life applications of constrained optimization.arrow_forwardIn Example 3, if the accountant earns a profit of 100 on each individual return and a profit of 175 on each business return, find the maximum profit. An accountant prepares tax returns for individuals and for small businesses. On average, each individual return requires 3 hours of her time and 1 hour of computer time. Each business return requires 4 hours of her time and 2 hours of computer time. Because of other business considerations, her time is limited to 240 hours, and the computer time is limited to 100 hours. If she earns a profit of 80 on each individual return and a profit of 150 on each business return, how many returns of each type should she prepare to maximize her profit?arrow_forwardIn Example 5, the candy manufacturer improves the production of chocolate-covered creams so that the profit is $2.50 per box. The constraints do not change. What is the maximum monthly profit? How many boxes of each type are produced per month to yield the maximum profit?arrow_forward
