Let's define variables:
x: number of times the ticket price increases ($ 1).
The income is given by:
I(x) = (15 + x)(500-20x)
We can rewrite this function in the following way:
I (x) = - 20x ^ 2 + 200x + 7500
We use the following equation to find the maximum:
max = (-b)/(2a)
where:
then, we have:
max = (-200)/(2(-20))
max = (200)/(40)
max=5
Thus, the ticket price that maximizes the benefit is:
15 + x = 15 + 5 = 20 $
Answer:
A ticket price that will maximize the charity's profit, if there are total 500 seats in the concert hall is:
$ 20
At the rate of 84 words per 2 minutes, which translates to 42 words per one minute.
So in one minute she types 42*1=42 words
In 3 minutes she types 42*3=126 words
In 9 minutes she types 42*9=378 words
On the month of February, 2,940 books will be published. However, if February falls on a leap year which has 29 days, about 3,045 books will be published.
Answer:
<em>F</em>
Step-by-step explanation:
Simplify then graph it, find the x-intercept.
y = 3.75 + 1.5 (x - 1)
y = 1.5x + 2.25
When graphed, the x-intercept is 1.5
So it is, $1.50 per mile
13.04, 13.06, 13.4, 13.6, 13.12
I think that’s right
