A summer camp cookout is planned for the campers and their families. There is room for 450 people. Each adult costs $7, and each camper costs $4. There is a maximum budget of $1,150. 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. (1 point)

x + y ≤ 1,150
7x + 4y ≤ 450

x + y ≤ 450
7x + 4y ≤ 1,150

x + y ≤ 1,150
4x + 7y ≤ 450

x + y ≤ 450
4x + 7y ≤ 1,150
