Revenue from Monorail Service, Las Vegas In 2005 the Las Vegas monorail charged $3 per ride and had an average ridership of abou
Karolina [17]

Answer:

A)The required linear demand equation ( q ) = -4500p + 41500

B) $4.61

   $95680.55

C) No it would not have been possible by charging a suitable price

Step-by-step explanation:

<u>A)  find the linear demand equation</u>

given two points ; ( 3, 28000 ) and ( 5, 19000 )

slope ( m ) = ( y2 - y1 ) / ( x2 - x1 )

                 = ( 19000 - 28000 ) / ( 5 - 3 )  = -4500

slope intercept is represented as ; y = mx + b

where y( 28000) = -4500(3) + b

  hence b = 41500  

hence ; y = -4500x + 41500

The required linear demand equation ( q ) = -4500p + 41500   ----- ( 1 )

p = price per ride

<u>B ) Determine the price the company should charge to maximize revenue from ridership  and corresponding daily revenue</u>

Total revenue ( R ) = qp

                               = p ( -4500p + 41500 )

  hence R = -4500p^2 + 41500p  ------ ( 2 )

To determine the price that should maximize revenue from ridership we will equate R = -4500p^2 + 41500p  to a quadratic equation R(p) = ap^2 + bp + c

where a = -4500 ,  b = 41500 , c = 0

hence p = -\frac{b}{2a}  = - \frac{41500}{2(-4500)} =  4.61

$4.61 is the price the company should charge to maximize revenue from ridership

corresponding daily revenue = R = -4500p^2 + 41500 p

where p = $4.61

hence R = -4500(4.61 )^2 + 41500(4.61) = $95680.55

C) No it would not have been possible by charging a suitable price

3) For what price is 15 percent off the same as $75 off?
Kryger [21]

\text{In this question, you would need to find the right value that 15\% is \$75}\\\\\text{You can do this by multiplying each number by 0.15}:\\\\200*0.15=30\\\\300*0.15=45\\\\350*0.15= 52.5\\\\500*0.15=75\\\\\text{You would see that 15\% of 500 is \$75}\\\\\boxed{\$500}

The shortest board available at the lumber yard is 3 feet long. How many 4 inch lengths can a carpenter get from the available b
MrRissso [65]

Answer:

Total of 9 lengths of 4 inches can be taken out from a board of 3 feet

Step-by-step explanation:

length of board in feet = 3 ft

As

1 ft = 12 inches

So

Length of board in inch =  3\times 12

                                       = 36 inches

Let no of 4 inches length be = x

The equation become

x \times 4= 36\\x= \frac{36}{4} \\x= 9

Total of 9 lengths of 4 inches can be taken out from a board of 3 feet

son4ous [18]

Hey there!

y = -1/4x + 10

Looking for the amount of hours of sleep for an 8 year old, so x is 8.

Solve for y:

y = -1/4(8) + 10

y = -2 + 10

y = 8

The predicted number of average hours of sleep for an 8 year old is 3. 8 hours.

Hope this helps!
