A group of retailers will buy 104 televisions from a wholesaler if the price is $300 and 144 if the price is $250. The wholesale
stepladder [879]

Answer:

The required equilibrium point is (356.538,58.769)

Step-by-step explanation:

The two points on your demand equation are : (300,104) and (250,144)

Take the number of televisions on y-axis and the price of the television on x-axis

Now, to find the demand equation for the given problem, find slope using the above two points :

\implies Slope=\frac{144-104}{250-300}\\\\\implies Slope = -\frac{4}{5}=-0.8

And the y - intercept is : y = -0.8x + b

Find the value of b using any point. Let us take (250,144)

144 = -0.8 × 250 + b

⇒ b = 144 + 200

⇒ b = 344

So, the y-intercept is : y = -0.8x + 344

The two points on your supply equation are : (225,88) and (315,68)

Take the number of televisions on y-axis and the price of the television on x-axis

Now, to find the supply equation for the given problem, find slope using the above two points :

\implies Slope=\frac{68-88}{315-225}\\\\\implies Slope = -\frac{2}{9}

And the y - intercept is :

y = -\frac{2}{9}x + b

Find the value of b using any point. Let us take (225,88)

88 = -\frac{2}{9}\times 225 + b\\\\\implies b = 88 + 50\\\\\implies b = 138

So, the y-intercept is :

y = -\frac{2}{9}x + 138

To find the equilibrium point, solve both the y-intercepts of the demand equation and the supply equation :

⇒ x = 356.538 and y = 58.769

Hence, the required equilibrium point is (356.538,58.769)

Please solve the question and give correct answer with explanation so that i can understand it​
denis-greek [22]

Answer:

  • Yes

Step-by-step explanation:

Let the speed of the car is c and speed of the plane is p.

<h3>We are given:</h3>

The speed of the plane is 7 times the speed of the car

  • p = 7c

The distance traveled is

  • d = 315 km

The time difference to travel this same distance is 3 hours.

<h3>We know that:</h3>
  • d = ts, where d- distance, t- time, s - speed

Find the time for car and plane and their difference.

<h3>Car</h3>
  • t = d/s = 315/c
<h3 /><h3>Plane</h3>
  • t = d/s = 315/p = 315/(7c) = 35/c
<h3 /><h3>The difference</h3>
  • 315/c - 45/c = 3

<u>Solve it for c:</u>

  • (315 - 45)/c = 3
  • 270/c = 3
  • c = 270/3
  • c = 90 km/h

Now find the speed of plane:

  • p = 7c = 7*90 = 630 km/h

As we see, Jenny is right
