Addyson's goal is to spend less than $415 on a trip. So far, she has spent $25 on gas for her car. She will spend $100 each day on other expenses. Addyson's trip must last fewer than how many days?

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.
