A high school club has a performance, with 800 tickets to sell. Tickets are $6 before the day of the show, and $9 on the day of the show. They must sell $5000 in tickets. How do I write a system of inequalities to represent the equation?

Answer 1

If x sold early, and y sold on the day, then

x+y <= 800
6x+9y >= 5000
