Answer:
38 and 57
Step-by-step explanation:
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
Where is the graph? But I guess the one that looks linear?
y-axis
That last sentence though, I died reading that.
<span>36 pieces of ribbon is what you can get from the 5 rolls. Each roll is 9 feet and 1 foot= 12 inches so we multiply 9 times 12 to get the total number of inches available per roll (108 inches) then times that by 5 the total number of rolls. This brought the total to 540 inches available for the project and divide that by 15 inches and end at 36 pieces.</span>
