Mustafa’s soccer team is planning a school dance as a fundraiser. the dj charges $200 and decorations cost $100. the team decides to charge each student $5.00 to attend the dance. if n represents the number of students attending the dance, which equation can be used to find the number of students needed to make $1,500 in profit?

40 students makes for the DJ.
20 students makes for the decorations.
300 students makes for the profit.
so there was 360 students that went to the dance.
