Answer:
60 guests
Step-by-step explanation:
We'll say that the number of guests is n.
We're looking for the n where both of these expressions are equal:
Company A (500 set-up fee, 25 for each guest)
500 + 25 * n
Company B (200 set-up fee, 30 for each guest)
200 + 30 * n
500 + 25n = 200 + 30n
Subtract 200 from both sides.
300 + 25n = 30n
Subtract 25n from both sides.
300 = 5n
We'll reverse the sides.
5n = 300
Divide both sides by 5.
n = 300/5 = 60
Thus, both companies are equal when n is 60, or when there are 60 guests.
Answer:
answer i d
Step-by-step explanation:
I think you meant for the three plays. If I'm incorrect, leave a comment below this answer and I'll edit my answer.
Play One = + 7 yards.
Play Two = - 15 yards.
Play Three = -18 yards
Net = 7 - 15 - 18 = - 26 yards. That means that they are 26 yards behind where the ball started for the first play. They are not in a very good position.
Answer:
a) $985
b) 89 people
Step-by-step explanation:
a) For this problem, we are given n, and we solve for C(n).
C(n) = 400 + 5n
= 400 + 5*117
= $985
b) For this problem, we are given C(n), and we solve for n.
C(n) = 400 + 5n
845 = 400 + 5n
845-400 = 5n
445 = 5n
n = 89 people
Answer:
X= 9
Y = -6
Step-by-step explanation:
first of all setting up the equation and solve it like a system of linear equations
5x+4y=21
-3x+2y=-39
then multiply -2 on the entire second equation
5x+4y = 21
6x-4y= 78
then eliminate the 4ys and you get
11x = 99
x = 9
lastly subsititue the 9 back into one of the original equations
5(9) + 4y =21
45 + 4y = 21
4y = -24
y = -6
