For a field trip, a bus company charges a flat fee plus an additional fee per student. For 25 students, the total cost is $167.50. If there are 70 students, the total cost is $370.00. Write an equation that represents the total cost y of the field trip for x students. What would the total cost be if 110 students went on the field trip?

cost=flat+numberkids*costperkid
370=flat+70*costperkid
167.5=flat+25*costperkid
subtract second equation from first..
370167.5=45*costperkid
solve for costper kid, then go back and solve for flat.
