Henry is starting a t-shirt printing business and plans on selling each shirt for $30, with his cost being $8 per shirt. The equipment will cost $1200.

Henry orders 600 shirts and determines that the profit for his new business is modeled by the function P = 22x - 1200. What is the domain of this function in this context?

In this context, the domain of the function represents the possible values for the number of shirts that Henry can sell. Since he ordered 600 shirts, that is the maximum number of shirts he can sell. Therefore, the domain of the function is 0 ≤ x ≤ 600.

This means that Henry can sell anywhere from 0 to 600 shirts in his t-shirt printing business.
