Assignments and Methods of Evaluating Student Progress:
1. Typical Assignments
a. A company manufactures and sells x television sets per month. The monthly cost and pricedemand equations are
C ( x)  72,000  60 x
x
p  200 
0  x  6,000
30
(a) Find the maximum revenue.
(b) Find the maximum profit, the production level that will realize the maximum profit, and the
price the company should charge for each television set.
b. The weekly marginal cost of producing x pairs of tennis shoes is given by
C ' ( x)  12 
500
x 1
where C(x) is cost in dollars. If the fixed costs are $2,000 per week, find the cost function. What
is the average cost if 1,000 pairs of shoes are produced each week?
c. A firm produces two types of calculators, x thousand of type A and y thousand of type B per
year. If the revenue and cost equations for the year are (in millions of dollars)
R ( x, y )  2 x  3 y
C ( x, y)  x 2  2 xy  2 y 2  6 x  9 y  5
determine how many of each type of calculator should be produced per year to maximize profit.
What is the maximum profit?
