The distance (one loop) walking once around the track at Foley stadium is 400m or about 1/4 of a mile how many Loops (how many times around the track do you have to walk) if you want to walk 3 miles?

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.
