The revenue, in dollars. of a company that produces video game systems can be modeled by the expression 52 +
gtnhenbr [62]

Answer:

1). Profit = 3x - 180

2) Profit of selling 1000 video games = $2820

Step-by-step explanation:

Expression for the revenue = 5x² + 2x - 80

Expression for the production cost of the video games = 5x² - x + 100

Since, profit is the difference between the revenue and the cost,

Expression for the profit will be,

Profit = Revenue - Cost

         = (5x² + 2x - 80) - (5x² - x + 100)

         = 5x² + 2x - 80 - 5x² + x - 100

         = 3x - 180

Here, x = Number of video games sold

If number of video games sold = 1000

Profit = (3×1000) - 180

         = 3000 - 180

         = $2820
