This document discusses sales mix, which is the relative proportion of different products or services sold by a company. Sales mix is important because products have different costs, selling prices, and profit margins. The sales mix strategy determines the optimal balance of products to maximize overall profits. An example shows how analyzing the sales mix of hamburgers and cupcakes at a cafe can reveal which items have higher margins and should be emphasized. Managing the sales mix is a strategic decision that can help businesses meet profitability targets.
