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 β 130. The cost, in dollars, of producing the skateboards can be modeled by 2x3 β 3x β 520. The variable x represents the number of skateboards sold. What expression represents the profit?
A. 27x β 650
B. 27x + 390
C. 33x β 650
D. 33x + 390
