If more than 20 people go everyone's fare is reduced by \$0.30 for each passenger over this number (20). At least how many people must go to make the fare less than \$7.50 per passenger?Answer by josmiceli(9697)   (Show Source): You can put this solution on YOUR website!Let = number of passengers over 20 who must go in order to make the fare less than \$7.50 per passenger ---------------- The fare /passenger gets reduced by exactly dollars if passengers above 20 go. The total number of passenger is ---------------- (normal cost) - (discount) = (desired cost) (nearest whole number) ----------- If 26 people go, fare is (fare/person)x(number of people) If 27 people go fare is (fare/person)x(number of people) It looks like 27 people must go to make fare less than \$7.50 per person
