The Current Procedural Terminology book contains medical codes that are often called CPT codes or National Level I codes. These CPT codes depict procedures and services that can be performed by physicians, surgeons, specialists, and ancillary staff.
Formula of Variable Cost. The formula to calculate variable cost is: Total Variable Cost = Total Quantity of Output * Variable Cost Per Unit of Output. To recognize variable costs, it is important to understand how to categorize costs.Variable costs are those which do not remain constant, specifically when production activities fluctuate.ormula of Variable Cost. The formula to calculate variable cost is: Total Variable Cost = Total Quantity of Output * Variable Cost Per Unit of Output. To recognize variable costs, it is important to understand how to categorize costs.
Total cost in economics includes the total opportunity cost of each factor of production as part of its fixed or variable costs. The rate at which total cost changes as the amount produced changes is called marginal cost.This is also known as the marginal unit variable cost.abor is the variable input, meaning that the amount of labor used varies with the level of output. In fact, in the short run, the only way to vary output is by varying the amount of the variable input. Labor is denoted L and the per unit cost, or wage rate, is denoted w, so the total variable costs is Lw.
