Let $R$ represent a company's revenue, let $C$ represent the company's costs, and let $x$ represent the number of units produced and sold each day. (a) Find the firm's break-even point; that is, find $x$ so that $R=C$ (b) Solve the inequality $R(x)>C(x)$ to find the units that represent a profit for the company. $$ \begin{array}{l} R(x)=12 x \\ C(x)=10 x+15,000 \end{array} $$

Key Concepts

Revenue Function

A revenue function represents the total income generated by the sale of goods or services. It is typically modeled as the product of the unit price and the quantity sold, which allows businesses to predict income based on sales volume and price per unit.

Cost Function

A cost function models the total cost incurred in producing and selling goods or services. This function often includes both fixed costs, which do not change with the level of output, and variable costs, which vary directly with the quantity produced.

Break-Even Analysis

The break-even point is the production level at which total revenues equal total costs, meaning the business neither makes a profit nor incurs a loss. This concept is crucial for understanding how many units need to be sold to cover all fixed and variable costs.

Profit Inequality

Profit inequality involves determining the conditions under which the revenue exceeds the costs, thereby resulting in a profit. This is typically done by setting up and solving an inequality where the revenue function is greater than the cost function, identifying the range of output levels that yield a profit.
