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?

Answer 1

Answer:

$50,700

Step-by-step explanation:

Answer 2

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 <==
