Final answer:
The Blair children should consider factors such as target market alignment and market demand when expanding their product mix.
Step-by-step explanation:
The Blair children are considering expanding their product mix. When expanding their product mix, they should avoid including options that are not aligned with their target market or brand identity. For example, if the Blair children's brand is known for selling eco-friendly products, they should not include options that are harmful to the environment.
Additionally, it is important for the Blair children to carefully evaluate the market demand and competition for each potential product. They should avoid including options that have low market demand or are already saturated with competitors.
In summary, the Blair children should consider factors such as target market alignment and market demand when expanding their product mix, and exclude options that do not meet these criteria.
