The math club is selling gift wrap for a fundraiser. they sold all 45 rolls of solid wrapping paper at $4 each and rolls of patterned wrapping paper at $5 each. if they made $265, how many rolls of patterned wrapping paper did they sell?

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
