            Suppose that a firm in a monopolistically competitive market has
a cost function of TC= 100,000 + 20Q.
- What is the marginal cost function?
 
- If the price elasticity of demand is currently -1.5, what price
should the firm charge?
 
- What is the marginal revenue at the price computed in part
b)?
 
- If a competitor develops a substitute product and the price
elasticity of demand increases to -3.0, what price should the firm
