In a linear cost function, the total cost is $x$ times the variable cost.

In a typical linear cost function, the total cost is a combination of fixed costs and variable costs, often expressed as: $C(x) = \text{Fixed Cost} + (\text{Variable Cost} \times x)$ where $x$ represents the number of units produced or sold.
