Final answer:
To calculate commission rates, one needs to know either the total sales amount or the base salary plus commission structure. The percent commission rate is calculated by dividing the commission earned by the total sales amount and multiplying by 100. Without necessary details such as the sale price or the agreed-upon commission percentage, determining the commission from a given profit is not possible.
Step-by-step explanation:
The question presented is related to commission rates and profit calculation in a sales context, which falls under the category of business studies. Calculating commission rates is a mathematical process typically covered in business courses that deal with finance, sales, or economics.
To determine the commission rate given a profit amount, you would need to know the total sales amount or the base salary plus commission structure, if applicable. In general, the commission rate can be calculated by dividing the commission amount earned by the total sales amount and then multiplying by 100 to get a percentage. However, without this crucial information, we cannot accurately determine the commission rate.
For example, if a salesperson earns a $750 commission on a sale of a $15,000 car, the commission rate would be calculated as follows: ($750 / $15,000) * 100 = 5%. Similarly, to determine the commission on a car sold for a $990 profit, we would need to know the percentage rate of commission agreed upon.
Sketching a graph with AC (Average Cost), MC (Marginal Cost), and AVC (Average Variable Cost) curves requires an understanding of cost structures in economics. When a firm sells computers for $500, to assess whether it is making a profit or a loss, we would need additional information about the costs involved.
