Jamarcus has a $50 gift card to use at a store. He does not have any additional money to spend at the store. Jamarcus will purchase a belt that cost $8 and x number of shirts that cost $15 each. The function f(x) = 42 - 15x models the balance of the gift card after Jamarcus makes the purchases. What is the most appropriate domain of the function?

• All integers value of x

• All positive integers values of x

• 0 ≤ x ≤ 2 where x is an integer

• 0 ≤ x ≤ 3 where x is an integer
