In order to do this, you have to find your profit equation and then set it equal to 800, which is the profit you're seeking. when you subtract the cost from the revenue, the new equation (or the profit equation) is this:
p(x)= -.5x^2 + 60x -800. If you want your profit, p(x), to be $800, then you set your equation equal to 800 and solve it for x, the 2 values that will bring about that 800 profit. Those production levels, or values for x, are -22.5 and 142.5 Since you cannot have a negative production level, you need to produce 142.5 whatevers to make that profit.
Answer:
The answer is 21
Step-by-step explanation: You substitue 3 for C and 4 for D and craete the equation 
so you add 3+4=7 and you get 
which is 7 times 3 =21
Just put 4 as x in the equation and solve it. The new equation is:
sqrt(2*4)+1+3 = 0
Now we can solve it.
sqrt(2*4) becomes sqrt8:
sqrt8+1+3=0. -------> sqrt8+4=0
The sqrt of 8 is about 2.83.. so 2.83+4 is:
6.83
So we have 6.83 as the answer
but 6.83 does not equal 0 so x cannot equal 4

Step-by-step explanation:
A coefficent is the number in front of the letter and a constant is just a number
