1. Competitive market Practice problem Wheat farmer Joe has the cost function of C(q) 160,000 + 100q+q². The market for wheat is competitive and there are many farmers like this, with the same cost function. The demand function is Q = 15000 - 10p. = (a) In the short run, below which price should Joe shut down? (b) In the short run, there are 19 farmers like Joe (so 20 farmers in total). How much should Joe produce? What will the price be? (c) What is the price below which Joe would shut down in the long run? (d) How many farmers will operate in the long run? (e) What is the market elasticity of demand at long-run equilibrium point?

3. Profit maximization using total cost and total revenue curves Suppose Iyana operates a handicraft pop-up retail shop that sells cardigans. Assume a perfectly competitive market structure for cardigans with a market price equal to $25 per cardigan. The following graph shows Iyana's total cost curve. Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for cardigans for quantities zero through seven (including zero and seven) that Iyana produces.
