5. (Ch. 17 # 5) Sparkle is one firm of many in the market for toothpaste, which is in long-run
equilibrium.
a. Draw a diagram showing Sparkle’s demand curve, marginal revenue curve, average cost
curve, and marginal cost curve. Label Sparkle’s profit-maximizing output and price.
b. What is Sparkle’s profit? Explain.
c. On your diagram, show the consumer surplus derived from the purchase of Sparkle
toothpaste. Also show the deadweight loss relative to the efficient level of output.
d. If the government forced Sparkle to produce the efficient level of output, what would
happen to the firm? What would happen to Sparkle’s customers?

I believe I gave adequate data. It says that are in long-run equilibrium and they are in a monopolistically competitive market, because that's what the market for toothpaste is. I got the answer already, but thank you for your reply.
