15. The Student Council is preparing a budget for an upcoming fund-raising dance. They have decided to spend $225 for a light and sound show, $600 for refreshments, and $75 for decorations. These are the only expenses. Given that the Student Council estimates 400 students will attend the dance, what should be the price, per student, for admission to the dance if the Student Council wants to raise as close as possible to $500 after paying expenses?
