The profit equation is:

a) (Unit price* Q)+( cup nit) variable costs+ Total fixed cos t * s = Profit

b) (Unit tprice* Q)-(U Unit variable costs* Q)+Total fixed costs = Profit

c) (Unit price - Unit variable costs - Total fixed costs) Q = Profit.

d) (Unit price* Q)-(U) Unit variable cos t * s * Q Total fixed cos t * s = Proft .
