Answer:
f(x) = 9x - 1,200
Step-by-step explanation:
Let x represent the number of movie tickets sold.
9x will represent the profit made from selling movie tickets that day, since each ticket is 9 dollars.
To determine the profit, subtract 1,200 from 9x.
9x - 1,200 will represent the profit. Turn this into a function:
f(x) = 9x - 1,200 where x is the number of movie tickets sold and f(x) is the profit
