The profit is the difference between the revenue (sales) and the cost, if x units are produced and sold, we can write the following: P(x) = R(x) – C(x) Where: P(x) = profit from sale of x units. R(x) = revenue from sale of x units C(x) = cost of production and sale of x units Revenue = (price per unit)(number of units)= p.q The cost is composed of two parts, fixed costs and variable costs: • Fixed costs such as rent, utilities… remain constant regardless of the number of units produced. •
