Suppose that in a monopoly market the total cost per week of producing a high tech product is given by : C(x) = 2x2 + 100x + 3600
Suppose further that the weekly demand function for this product is :
P(x) = 500 – 2x
Where x is the number of units sold :
a. find the number of units that will give the break even points for the product?

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
