the revenue, in dollars, of a company that produces video game systems can be modeled by the expression 5x² + 2x - 80. the cost, in dollars, of producing the video game systems can be modeled by 5x² - x + 100, where x is the number of video game systems sold. if profit is the difference between the revenue and the cost, what expression represents the profit? profit can be modeled by the polynomial expression. if 1,000 video game systems are sold, the companys profit is $

the revenue, in dollars, of a company that produces video game systems can be modeled by the expression 5x² + 2x - 80. the cost, in dollars, of producing the video game systems can be modeled by 5x² - x + 100, where x is the number of video game systems sold. if profit is the difference between the revenue and the cost, what expression represents the profit? profit can be modeled by the polynomial expression. if 1,000 video game systems are sold, the companys profit is $

Answer

Explanation:

Step1: Define profit formula

Profit = Revenue - Cost

Step2: Substitute given expressions

Revenue = $5x^{2}+2x - 80$, Cost = $5x^{2}-x + 100$. So, Profit=$ (5x^{2}+2x - 80)-(5x^{2}-x + 100)$

Step3: Simplify the expression

[ \begin{align*} &(5x^{2}+2x - 80)-(5x^{2}-x + 100)\ =&5x^{2}+2x - 80 - 5x^{2}+x - 100\ =&(5x^{2}-5x^{2})+(2x+x)+(- 80 - 100)\ =&3x-180 \end{align*} ]

Step4: Calculate profit for $x = 1000$

Substitute $x = 1000$ into the profit - expression $3x-180$. Profit=$3\times1000-180=3000 - 180 = 2820$

Answer:

Profit can be modeled by the polynomial expression $3x - 180$. If 1,000 video - game systems are sold, the company's profit is $$2820$.
