Answer

Explanation:

Step1: Define profit formula

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

Step2: Calculate profit expression

Profit=$(5x^{2}+2x - 80)-(5x^{2}-x + 100)$ $=5x^{2}+2x - 80 - 5x^{2}+x - 100$ $=(5x^{2}-5x^{2})+(2x+x)+(-80 - 100)$ $=3x-180$.

Step3: Calculate profit when $x = 1000$

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

Answer:

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