Profit is the difference between revenue and cost. The revenue, in dollars, of a company that makes skateboards can be modeled by the polynomial 2x3 + 30x – 130. The cost, in dollars, of producing the skateboards can be modeled by 2x3 – 3x – 520. The variable x represents the number of skateboards sold. What expression represents the profit? 27x – 650 27x + 390 33x – 650 33x + 390

Option (d) is correct.

Explanation:

Given that,

Profit is the difference between revenue and cost.

Revenue of a company = 2x3 + 30x – 130

Cost of a company = 2x3 – 3x – 520

Profit = Revenue of a company - Cost of a company

         = (2x3 + 30x – 130) - (2x3 – 3x – 520)

         = 2x3 + 30x – 130 - 2x3 + 3x + 520

         = 33x + 390

the first option is the answer.
