Answer:
sole proprietorship
Explanation:
According to my research on different types of businesses, I can say that based on the information provided within the question Blake's form of business ownership is known as a sole proprietorship. This is a type of business in which a single person controls, runs, and owns the entire business and there is no legal difference between the owner and the business. In other words all legal incomes and debts are the responsibility of the owner. Which is the case in this scenario since Blake assumes unlimited liability for the business's bills and depts.
