Answer:
the first one.
Step-by-step explanation:
DJ and decorations are one time flat costs. they are constant. so, together, they are $300.
that is what decreases the profit.
on the other side, $5 per student = 5n in total increases our profit.
so, in total the sum of both (the decreasing amount has a negative sign, if course) :
5n - 300 = 1,500
is the right equation to calculate how many students are needed to make that much profit.
the solution, but the way :
5n - 300 = 1500
5n = 1800
n = 1800/5 = 360 students
