Which of the following pricing strategies involves determining price based on the relationship between costs and sales volume?

The concept of determining price based on the relationship between costs and sales volume is best exemplified by break-even analysis. This strategy focuses on calculating the point at which total revenues equal total costs, thus determining the minimum sales volume needed to avoid losses. By understanding the break-even point, businesses can set prices that not only cover their costs but also help to achieve desired profit levels as sales volumes increase.

In break-even analysis, the fixed and variable costs are considered in relation to the price point and expected sales volume. This allows businesses to visualize how changes in sales volume affect profitability and to make informed pricing decisions that align with their financial goals.

Cost-plus pricing, on the other hand, focuses on adding a specific markup to the cost of goods sold to determine the selling price, without directly analyzing sales volume's impact. Dynamic pricing involves adjusting prices in real-time based on demand and market conditions, rather than a static analysis of costs against sales volume. Pricing markups relate to adding a percentage to the cost of a product but do not take into account the sales volume relationship as explicitly as break-even analysis does.
