5) Mrs. Sevrey’s science classes are going to Glacier Park and then out for ice cream. There is no
admission fee for Glacier Park but the ice cream will cost $4.00 per student. The cost of the
busses for all of her classes is $300.00.
a) Write an equation or rule that represents the function.
b) Make a table that shows how much a
trip for 30 students, 60 students,
90 students, 120 students, and 150
students would cost.
