<h3>Variable cost function</h3>
- An expense for the company that varies according to how much is produced or sold is called a variable cost.
- Depending on a company's production or sales volume, variable costs grow or fall. They climb as production rises and reduce as production declines.
- It is a production cost whose level fluctuates in response to shifts in a business's manufacturing activities.
- For instance, the raw materials required to make a product's components are regarded as variable costs because they frequently change depending on the volume of units produced.
- The total variable cost curve depicts the relationship between total variable cost and the volume of output produced graphically.

The gross sales margin equals 42.76%
The formula to calculate the Gross Sales Margin is (Revenue - Cost of Goods Sold) / Revenue
Revenue = $137,500 + $425,600 = $563,100
($563,100 - 322,325) / 563,100 =
240,775 / 563,100 = 42.76%
