Answer:
Offer more tickets for the sell
Step-by-step explanation:
From the above condition we can observe that the average number of customer increases with the increase in the movie she shows. when she was showing only three movies the ticket price was cheaper but the customers were also less.
Then addition of a movie with raised ticket price still attracted more customer than average when three movies were sold. From these data we can conclude that she can offer more tickets for sale as the number of customers is increasing.
