Question

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions, can be modeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 -160x + 300. The variable x is the number of televisions sold. If 150 televisions are sold, what is the profit?

I want to know how to you solve it?

Answer 1

50,700

Explanation:

3x^2 + 180x - (3x^2 - 160x + 300) = profit

3x^2 + 180x - 3x^2 + 160x - 300 = profit

340x - 300 = profit

so if 150 televisions are sold...x = 150

340(150) - 300 =

50,700 <==
