You are creating a program for the organizer of an annual outdoor festival. (A state fair or something.) The festival takes place in a 500 square foot field and event has booths and attractions that take up a specified amount of square feet each year. Safety regulations state that when at max capacity, each person at the festival requires 5 sq ft of personal space. You need to create program that will calculate how many tickets can be sold for this event, given the amount of space needed for the festival attractions this year.
