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
udent
$15 for every one lap
$23.25 for every one lap
$7.75 for every one lap
$16.32 for every one lap
$19.50 for every one lap
$19.17 for every one lap
corrine had a total donation
of $228.50 after 14 laps.
y-228.5 = 7.75(x-14)
l
javier had a total donation
of $230 after 12 laps.
y-230 = 15(x-12)
sam had a total donation
of $186 after 8 laps.
y= 19.5x+30
