Suppose There are 100 identical firms in the perfectly competitive note card industry. Each firm has a short-run total cost curve of the form: STC = 1/300q3 + 0.2q2 + 4q + 10 and marginal cost is given by SMC = 0.01q 2 + 0.4q + 4

a) Calculate the firm's short run supply curve with q (the number of crates of note cards) as a function of market price (P).

b) Calculate the industry supply curve for the 100 firms in this industry.
