Incomplete question. I provided an explanation about the term, "business model."
Explanation:
Usually, when mention is made of the term business model it simply refers to the decided way a business plans to make profits.
In other words, it includes information about services or products to be offered by the business in other to keep the business alive, but not just been alive but to continue growing profit-wise.
Hence, we can say, Henry's business model should contain information about the dog charges which would be profitable to his business.
