題目如下
There is a perfectly competitive market for apples. There are 100 identical farms
in this industry and your farm is one of them. The industry’s demand function is
Qd=20,000-5000P .Your farm has a total cost curve of
TC=0.01q^2+q+100,
where q is pounds of apples your farm produces and sells daily.
a. What is the short run market equilibrium price? (4%)
b. What quantity you should produce for maximum profit? (4%)
c. What is this profit? (4%)
