Number of Firms (few, one, or many)
Types of product(differentiated, unique, anything, or standardized)
Entry (challenging, impossible, or easy)
Market model (perfect competition, monopoly, monopolistic competition, or oligopoly)

Answer 1

Number of firms: many. There are dozens of companies offering tutoring services, so we can safely say that the number of firms in this market is many.

Types of product: standardized. Consumers of this market, who are the students, view the quality of all algebra tutoring companies as being essentially the same.

Entry: easy. The only requirement to enter this market is to be able to teach algebra, so as long as a person knows algebra, this person would in theory be able to enter the market.

Market model: perfect competition. The market of algebra tutoring services in this case is closest to perfect competition. Both buyers and sellers are plenty, so neither can excercise market power. The product offered is standardized, which means that each firm's tutoring service is a perfect substitute for the tutoring services of the other firms. Finally, barriers of entry and exit are almost non-existant.
