Chapter 8, Problem 40P

Perfectly competitive firm Doggies Paradise Inc. sells winter coats for dogs. Dog coats sell for $\$\text{72}$ each. The fixed costs of production are $\$\text{1}0\text{9}$.

The total variable costs are $\$\text{54}$ for one unit, $\$\text{84}$ for two units, $\$\text{114}$ for three units, $\$\text{134}$ for four units, and $\$\text{27}0$ for five units. 111 the fauna of a table, calculate total revenue, marginal revenue, total cost and marginal cost for each output level (one to five units). On one diagram, sketch the total revenue and total cost curves. On another diagram, sketch the marginal revenue and marginal cost curves. What is the profit maximizing quantity?
