Quadratics - A computer manufacturer

Question

a computer manufacturer found that when it produces computers in 1 month the profit for the month P(x) was approximated by P(x)= -0.05x^2 +350x - 36000. How many computers were produced if the company profit for 1 month was $225,000

Answer 1

Hi Abbey W

Since you are given P(x) = 225000 for 1 month, you set your function equal to that, move everything over to one side of the equation and use the Quardratic Formula to find x. Keep in mind profit occurs on the upswing.

Give that a try.
