Seven students took a bus to the state park. the round-trip tickets cost $45 per student. they stayed for a few nights at a campground at a cost of $5 per student each night. which missing information is needed to find the total amount each student spent on the camping trip?

good luck on your studies! : )

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
