Total revenue is a straight line from the origin with

faces a downward sloping demand curve

Unlike a perfectly competitive firm, a monopoly

more elastic in the long run. (Elasticity tends to be greater in the long run since the firm will be able to adjust to changes in demand. The firm will have more options in availability of resources in order to substitute less expensive resources (inputs) for more expensive resources in the long run).

Usually, the supply curve of firms operating under conditions of perfect competition in product market would be identified as

those that do change with output

Variable costs are
