Question 553435: A theater�s maximum capacity is 425 people. The cost of admission to a play at the theater
is $29. The revenue function R = 29n, in which n is the number of tickets sold, represents
the amount of income from admissions for one performance. What values of n represent a
reasonable domain for the revenue function in this situation?
it is5 either.... [A] any real number such that 0 less than or equal to n, n is less than or equal to 425 (cant type in the signs) [C] any whole number such that 0 is less than or equal to n, n is less than or equal to 425
thought is was the whole number answer but everywhere i check it says should be a real number... what is the difference?
