The seventh grade math classes are going on a field trip. The field trip will
cost the school $7 per student plus a one time fee of $55 for a bus to rent.
The total cost of the field trip was $307. Write an equation to find the total
number of students that went on the field trip.
62s = 307
55s + 7 = 307
7s + 55 = 307
75 -55 = 307
