The cost function for a certain company is C = 20x + 700 and the revenue is given by R = 100x − 0.5x2. Recall that profit is revenue minus cost. Set up a quadratic equation and find two values of x (production level) that will create a profit of $700.

The two values of production level are:

x = 20

or

x = 140

Step-by-step explanation:

Let's write the Profit equation by subtracting the cost function from the revenue one:

Now, we set to find the production level "x" to give us a profit of $ 700:

So we solve this quadratic equation using the quadratic formula:

which gives two posible solutions: x = 20, or x = 140

we need the options

step-by-step explanation:

answer: 140

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
