Question

The revenue of the company is given by the equation R = x (1000 – 4x), where R is the   revenue of the company in dollars when thy sell x units of a product. How many units of the product should they sell to make revenue of $60,000?

Select one:

a. 150,100 

b. 150,300

c. 200,100​

Answer 1

x(1000-4x) = 60000

1000x - 4x^2 = 60000

A quadratic equation

-4x^2 + 1000x - 60000 = 0

simplify, divide by -4

x^2 - 250x + 15000 = 0

factors to

(x-100)(x-150) = 0

two solutions

x = 100 units

and

x = 150 units, both will make you $60,000

Answer 2

A) 150,100
