Revenue
Revenue is price multiplied by units sold in a simple one-product model.

Contribution per unit is selling price minus variable cost per unit.
Break-even
Break-even units = fixed cost / contribution, rounded upward for whole units.
Limits
Demand, taxes, financing and other costs may be outside a classroom model.
