Instead of words. The PTA of Northside High School sells burgers at the home basketball games to raise money for new uniforms. For each game,
they purchase enough supplies to make 80 burgers. The hamburger patties cost $60, the cheese slices cost $15, and the buns
cost $25. They sell the burgers for $4 each, regardless of whether or not the customer asks for cheese.
The profit for the burger sales is graphed below. Let x represent the number of burgers sold, and let y represent the profit, which is
the amount of money raised for the new uniforms.
