When a business wants to increase it's revenue should it raise it's price?

expanding all inputs does not change the average cost of production.

price of competing products
Why would labor be treated as a variable cost?
producing larger quantities of a good or service generally requires more workers
Idaho farmers can sell as large a quantity of their potato crop as they wish,
provided each is willing to accept the prevailing market price.

For a perfectly competitive firm, the marginal cost curve is identical to the firm�s ________________ .
supply curve
If it was possible for one company to gain ownership control all of the uranium processing plants in the US, then
that firm could set up barriers to entry to discourage competition.
