Fixed Cost: the cost that a business incurs even if the plant is idle and output is zero. Also known as “overhead”

Variable Cost: a cost that changes with output…associated with labor and raw materials

Variable Cost: a cost that changes with output…associated with labor and raw materials

Cost What is the equation total cost? FC + VC = TC

Cost What is the equation total cost? FC + VC = TC

Total Cost: sum of variable cost plus fixed cost; all costs associated with production.

Total Cost: sum of variable cost plus fixed cost; all costs associated with production.

Profit-Maximizing Quantity of Output : Level of production where marginal cost is equal to

Profit-Maximizing Quantity of Output : Level of production where marginal cost is equal to marginal revenue

Profit Maximizing = MR = MC • Profit-Maximizing quantity of output: MR = MC
