Answer:
a) $50,880
b) $48
c) 1060
Step-by-step explanation:
a)
-320x^2 + 1920x + 48000 = 0
This is a parabola that opens downward. It has a maximum value. The maximum value occurs at x = -b/(2a)
x = -b/(2a) = (-1920)/(2(-320)) = 1920/640 = 3
The maximum revenue, y, is the value of the function evaluated at x = 3.
f(x) = -320x^2 + 1920x + 48000
f(-3) = -320(3)^2 + 1920(3) + 48000
f(-3) = 50,880
The maximum revenue is $50,880
b)
Since maximum revenue occurs at x = 3, and since x represents the number of $4 discounts, the discount is 3 * $4 = $12. The price is $60 - $12 = $48
c)
$50,880/$48 = 1060
34(3-2)9x-2 = 14 would be the correct way to solve the problem!
5 friends have 1/2 of a pie left. If each person wants an even share, how much pie will each of them get?
Answer: A
Step-by-step explanation:
It’s A bc the other answers are not accurate for this problem lol
x + 21 + 3x + 9 = 90
Combine like terms
4x + 30 = 90
Subtract 30 from both sides
4x = 60
Divide both sides by 4
x = 15
