Unformatted text preview: a short-run total cost curve of the form: tc(x) = (1/300)x 3 + 0.2x 2 + 4x +10. a. Assuming all fixed costs are sunk costs, calculate the firm’s short-run supply curve with x as a function of the market price P. b. Given there are 100 firms, calculate the short-run industry supply curve with X as a function of P. c. Suppose the market demand is given by X D = 8,000- 200P. What will be the short-run equilibrium price and quantity combination? That is, find the following: P*, X* and x*. d. Is this short-run equilibrium also a long-run equilibrium price and quantity combination? Why or why not?
