Question 1050582: The freshman class is planning a field trip to the American Museum of Science and Energy in Oak Ridge. The cost for 12 students is $36 and the cost for 25 students is $75.
Which equation shows how the cost, y, is related to the number of students,x?
F y = x H = 12x + 36
G y = 3x J = y = 25x + 12

You can put this solution on YOUR website!
y%2812%29=36
y%2825%29=75
.
.
m=%28y%2825%29-y%2812%29%29%2F%2825-12%29=%2875-36%29%2F%2825-12%29=39%2F13=3
.
.
So then using the point-slope form,
y-36=3%28x-12%29
y-36=3x-36
y=3x
The cost of a ticket is $3 per student.
