A summer camp cookout is planned for the campers and their families. there is room for 525 people. each adult costs $9, and each camper costs $5. there is a maximum budget of $1,200. write the system of inequalities to represent this real-world scenario, where x is the number of adults and y is the number of campers. x y ≤ 525 5x 9y ≤ 1,200 x y ≤ 1,200 5x 9y ≤ 525 x y ≤ 525 9x 5y ≤ 1,200 x y ≤ 1,200 9x 5y ≤ 525
