Question

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?

Answer 1

The answer should be 33x -390

Answer 2

Answer:

$33x+390$

Step-by-step explanation:

Given that revenue, in dollars, of a company that makes skateboards can be modeled by the polynomial

$2x^3 + 30x - 130$.

The cost, in dollars, of producing the skateboards can be modeled by

$2x^3 - 3x - 520.$

Profit function = Revenue - cost

= $2x^3 + 30x - 130-(2x^3 -3x - 520)\\=33x+390$

So profit function in terms of x

= $33x+390$
