Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. 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.

$16.32 for every one lap
$15 for every one lap
$7.75 for every one lap
$19.17 for every one lap
$19.50 for every one lap
$23.25 for every one lap
Sam had a total donation
of $186 after 8 laps.
y = 19.5x + 30

Javier had a total donation
of $230 after 12 laps.
y - 230 = 15(x - 12)

Corrine had a total donation
of $228.50 after 14 laps.
y - 228.5 = 7.75(x - 14)
