The average ticket price for a concert at the opera house was $50. The average attendance was 4000. When the ticket price was ra

kotegsom [21]

Answer

given,

opera house ticket = $50

attendance = 4000 persons

now,

opera house ticket = $52

attendance = 3800 person

assuming these are the points on the demand curve

(x, p) = (4000,50) and (x,p) = (3800,52)

using point slope formula

$p-50 = \dfrac{50-52}{4000-3800}(x - 4000)$

$p-50 = \dfrac{-2}{200}(x - 4000)$

$p-50 = \dfrac{-x}{100}+ 40$

$p = \dfrac{-x}{100}+ 90$

R(x) = x . p

$R(x) = x (\dfrac{-x}{100}+ 90)$

$R(x) = \dfrac{-x^2}{100}+ 90x)$

$\dfrac{d}{dx}(R(x)) = \dfrac{d}{dx}(\dfrac{-x^2}{100}+ 90x))$

$\dfrac{d}{dx}(R(x)) = (\dfrac{-2x}{100})+90)$

at $\dfrac{d}{dx}(R(x)) = 0$

$\dfrac{-2x}{100}= -90$

x = 4500

$\dfrac{d^2}{d^2x}(R(x)) = -ve$

hence at x =4500 the revenue is maximum

for maximum revenue ticket price will be

$p = \dfrac{-4500}{100}+ 90$

p = $45

When a number is decreased by 19% the result is 66 what is the original number to

dybincka [34]

Answer:

The original number is x = 66 .19

Step-by-step explanation:

Let 'x' be the number

Given data a number is decreased by 19% the result is 66

x - 19% = 66

x-0.19 = 66

Adding '0.19' on both sides , we get

x - 0.19 +0.19 = 66 +0.19

x = 66 .19

The original number is x = 66 .19

Jlenok [28]

Answer:

Slope-intercept is y=-x/3

The slope is -1/3

The y-intercept is 0

Step-by-step explanation:

First, we need to put this as slope-intercept for which is y=mx+b

3y=-x

y=-x/3
