4. A furniture store manufactures executive desks. It is estimated that the

total cost of making x desks is given by C(x)=100x + 200,000

dollars per year.

a. Research and find a function that will give the average cost of making

desks (Hint: The symbol,-C(X) , is used to represent the average cost; think

of how the numbers were averaged).

b. Evaluate the lim x-> infinity -C(x)

c. What does this tell you about the advantages that a large chain has over a

small, local producer?
