The production of a particular good requires a unique plant size. The daily fixed costs are $40 and no individual plant can produce more than 20 units per day. The variable costs are = $3 (where q is firm-specific output, not market output Q). Firms can operate multiple plants (if desired). Describe and demonstrate (diagrammatically,mathematically) the short-run and the long-run cost curves for this firm. A complete answer must include applicable correct, careful diagrams, analytical demonstrations, and explanation
