Answer:
Step-by-step explanation:
- With the equation's current format, we will have trouble solving with all these fractions. Especially the fraction is very difficult to deal with, so my first step would be:
- If we multiply both sides by this number, we will be able to get rid of the messy fraction on the right side as well as remove the fraction on the left side. Like so:
- <em>I put the I multiplied onto each side in fraction form simply for clarity. You do not need to do this.</em>
- After this point, let's put our variable, , onto one side of this equation and any other integers on the other by adding and subtracting them from both sides.
- Now we divide so that is isolated, and we are done.
The answers are
- A. The equation for the profit from selling the items is P = 40x-0.5x²-300.
- b. The values of x are 10 and 70.
- c. It is not possible to have the profit of 2500
<h3>How to solve for the expression</h3>
We have the cost function in this question to be
C(x) = 60x+300
We have the function of the revenue to be
Revenue = 100x−0.5x²
A. The formula for revenue function is given
revenue - cost
This is expressed as
= (100x−0.5x²)-60x+300
We have to collect like terms and open the equation above.
This given us:
<h3>40x-0.5x²-300</h3>
B. when profit = 50$
We have p = 40x-0.5x²-300
50 = 40x-0.5x²-300
Multiply the two sides by 10
This gives
500 = 400x - 5x² - 3000
This gives a quadratic equation
5x² - 400x - 3500 = 0
To solve the equation you have to make use of a quadratic calculator.
This gives us the values
<h3>x = 10</h3><h3>x = 70</h3>
c. We have P = 40x-0.5x²-300.
at P = 2500
2500 = 40x-0.5x²-300.
Multiply the equation by 10
25000 = 400x - 5x² - 3000
collect like terms
400x - 5x2 - 3000 +28000
400x -5x2 +28000
We have to take the discriminant
-400² - 4*5*28000
= -400000
The discriminant is negative hence it is not possible.
