Use the demand schedule that follows to answer questions 1, 2, and 3.
1. Calculate total revenue and marginal revenue at each quantity.
2. Use Chapter 4's total-revenue test for price elasticity to determine at which price levels the demand is elastic and inelastic.
3. Suppose the marginal cost of successive units of output were $3.50. What output would the profit-seeking firm produce and what price would the firm charge?

A book publisher initially prices both hardback books and paperback books at $20 per book. The hardback version comes out first, followed two months later by the paperback version. The publisher initially sells the same number of hardbacks and softbacks (100 each). A hardback book costs $3.00 to produce, and a paperback book costs $2.00 to produce.
