4. Profit is defined as earnings less expenses (earnings - expenses). At the local hot air balloon festival, the Ma & Pops Ice Cream Truck sells ice cream pops, which cost them $0.75 each, but are sold for $2 each. They also paid $50 to
the festival's organizers for a vendor permit. The table below shows the earnings, expenses, and profit earned
when 50, 75, and 100 ice cream pops were sold at the festival.
