Final answer:
Ebele is using stealth marketing to subtly promote Furaha flour to her baking class students, influencing their purchase decisions.
Step-by-step explanation:
In the given scenario, Ebele is using stealth marketing to increase her husband's sales. Stealth marketing, also known as undercover or buzz marketing, is a strategy where consumers are unaware that they are being marketed to. The technique involves promoting a product or service to people without them realizing it is an advertisement. Ebele incorporates the product into her baking classes by stating that "cakes baked with Furaha flour taste better," which influences her students to purchase the flour, often without recognizing the promotional intent behind her statement.
