Given:
Marginal revenue (in dollars per unit) for a month is
![MR=-0.5x+400](https://tex.z-dn.net/?f=MR%3D-0.5x%2B400)
To find:
The total revenue from the production and sale of 30 units.
Solution:
We know that, total revenue is integration of marginal revenue with respect to quantity.
![TR=\int MR dx](https://tex.z-dn.net/?f=TR%3D%5Cint%20MR%20dx)
![TR=\int (-0.5x+400) dx](https://tex.z-dn.net/?f=TR%3D%5Cint%20%28-0.5x%2B400%29%20dx)
![TR=-0.5\int x dx+400\int 1 dx](https://tex.z-dn.net/?f=TR%3D-0.5%5Cint%20x%20dx%2B400%5Cint%201%20dx)
![TR=-0.5\times \dfrac{x^2}{2}+400x](https://tex.z-dn.net/?f=TR%3D-0.5%5Ctimes%20%5Cdfrac%7Bx%5E2%7D%7B2%7D%2B400x)
Now, substitute x=30 in the equation of Total Revenue (TR).
![TR=-0.5\times \dfrac{30^2}{2}+400(30)](https://tex.z-dn.net/?f=TR%3D-0.5%5Ctimes%20%5Cdfrac%7B30%5E2%7D%7B2%7D%2B400%2830%29)
![TR=-0.5\times \dfrac{900}{2}+12000](https://tex.z-dn.net/?f=TR%3D-0.5%5Ctimes%20%5Cdfrac%7B900%7D%7B2%7D%2B12000)
![TR=-225+12000](https://tex.z-dn.net/?f=TR%3D-225%2B12000)
![TR=11775](https://tex.z-dn.net/?f=TR%3D11775)
Therefore, the total revenue from the production and sale of 30 units is $11,775.
Answer:
x = 3
Step-by-step explanation:
-5(3x -7) + 11 = 1
Distribute 5:
-15x + 35 + 11 = 1
Combine like terms:
-15x + 46 = 1
Subtract by 46 =
-15x = 1 - 46
-15x = -45
Divide by -15:
x = -45 / -15
x = 3
