A school puts on a play. The play costs $1,200 in expenses. The students charge $4.00 for tickets. There will be one performance of the play in an auditorium that seats 500 people. What is the domain of the function that shows the profit as a function of the number of tickets sold?

These are my options:

a) The domain is all real numbers from negative 1,200 to positive 2,000

b) The domain is all integers from negative 1,200 to positive 2,000.

c) The domain is the integers from 0 to 500.

d) The domain is all real numbers from 0 to 500
