A volunteer knits a 5-foot long scarf at a constant rate. After 4 hours, the volunteer still has to knit 3 feet of the scarf. How much time does it take to knit the scarf from start to finish? What is the rate of change in this situation, and write this out in a complete sentence (which means you must add context--tell me what the rate of change means in this situation)

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.
