The cost function for a certain company is C=60x+300 and the revenue is given by R=100x0.5x2. Remember that revenue less cost equals profit. Find two values of x (production level) in a quadratic equation that will result in a profit of $300.

Step 1
Given:
C=60x+300
R=100x0.5x2
Profit =$300, solve for x.
We know that:
Profit =RC
Step 2
Then,
300=(100x0.5x2)(60x+300)
300=100x0.5x260x300
300=0.5x2+40x300
0.5x240x+300+300=0
0.5x240x+600=0
12x240x+600=0
x280x+12002=0
x280x+1200=0
x260x20x+1200=0
x(x60)20(x60)=0
(x60)(x20)=0
x=20, 60
So final as:
The two values of x are 20 and 60

Answer:
x=20 and x=60
Explanation:
Profit is calculated by subtracting the cost from the revenue:
P=RC
Given that the cost function is C=60x+300 and the revenue function is R=100x0.5x2, we can substitute these expressions into the profit equation:
P=(100x0.5x2)(60x+300)
Simplifying this equation, we have:
P=100x0.5x260x300
Combining like terms:
P=0.5x2+40x300
We want to find the values of x that make the profit P equal to 300. Therefore, we set up the equation:
0.5x2+40x300=300
Rearranging the equation, we get:
0.5x2+40x600=0
This is a quadratic equation in standard form. To find the values of x that satisfy this equation, we can use the quadratic formula:
x=b±b24ac2a
In our case, the quadratic equation is:
0.5x2+40x600=0
Comparing this equation to the standard quadratic equation form, we can determine the values of a, b, and c:
a=0.5, b=40, and c=600
Substituting these values into the quadratic formula, we get:
x=40±4024(0.5)(600)2(0.5)
Simplifying further:
x=40±160012001
x=40±4001
x=40±201
Hence, we have two possible values for x:
x1=40+201=20
x2=40201=60
Therefore, the production levels that result in a profit of 300 are x=20 and x=60.

Step 1:
The cost function is given as C=60x+300, and the revenue function is given as R=100x0.5x2.
The profit function is defined as P=RC. Substituting the given cost and revenue functions, we have:
P=(100x0.5x2)(60x+300).
To find the values of x that result in a profit of 300, we set up the following equation:
300=(100x0.5x2)(60x+300).
Simplifying the equation, we have:
0.5x240x+600=0.
Step 2:
Now we have a quadratic equation. To solve it, we can use the quadratic formula:
x=b±b24ac2a.
Comparing the equation 0.5x240x+600=0 to the general form ax2+bx+c=0, we have:
a=0.5, b=40, and c=600.
Step 3:
Substituting these values into the quadratic formula, we get:
x=(40)±(40)24(0.5)(600)2(0.5).
Simplifying further:
x=40±160012001.
x=40±4001.
x=40±201.
Thus, the two values of x (production levels) that will result in a profit of 300 are:
x=20 and x=60.
