A soccer coach wants to take her team of 20 students to the state capital for a tournament. The travel agent says the trip will cost $125 per student, but the coach thinks this is too expensive. The travel agent suggests that the coach persuade other students to go with the team. For each extra student, the cost per student would be reduced by $1.
PLEASE HELP
