profit is the difference between revenue and cost. the 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 $2x^{3}-3x - 520$. the variable $x$ represents the number of skateboards sold. what expression represents the profit? 27x - 650 27x + 390 33x - 650 33x + 390
Answer
Answer:
D. $33x + 390$
Explanation:
Step1: Set up profit formula
Profit = Revenue - Cost Revenue = $2x^{3}+30x - 130$, Cost = $2x^{3}-3x - 520$
Step2: Substitute expressions
Profit=$(2x^{3}+30x - 130)-(2x^{3}-3x - 520)$
Step3: Remove parentheses
Profit = $2x^{3}+30x - 130 - 2x^{3}+3x + 520$
Step4: Combine like - terms
$(2x^{3}-2x^{3})+(30x + 3x)+(-130 + 520)=33x[Client Connection Error]
