Final answer:
A company uses an undifferentiated marketing strategy when it believes that the needs of the market can be met with a single marketing mix, which can be cost-effective and suitable for a broad audience.
Step-by-step explanation:
A company would use the undifferentiated marketing strategy because they believe that the needs of individual consumers in the target market are relatively homogeneous, and thus, the firm can satisfy the majority of customers with a single marketing mix. This approach can be more cost-effective, as it avoids the expenses associated with creating different products and marketing plans for various market segments. It's important to note, however, that this strategy works best when the product offered meets the needs of a broad audience without much alteration.
