Question

TIME REMAINING

Answer 1

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
