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
Answer:
no solution
Step-by-step explanation:
if you graph both equation the lines are parallel.
parallel = no solution
overlap = infinite solution
intersect = one solution
I = PRT/100
100I = PRT
P= 100I÷RT
P = 100I/RT
Step-by-step explanation:
when numbers are negative, the bigger the number looks the smaller it is therefore
-6 is smaller than -5
but 6 is bigger than 5
however, the numbers are;
-5.99, -3, -6, -5.9, -1, -5.999, -5 ,2
