the revenue, in dollars, of a company that makes toy cars can be modeled by the polynomial 3x^2 + 4x - 60. the cost, in dollars, of producing the toy cars can be modeled by 3x^2 - x + 200. the number of toy cars sold is represented by x. if the profit is the difference between the revenue and the cost, what expression represents the profit? 3x - 260 3x + 140 5x - 260 5x + 140
Answer
Explanation:
Step1: Recall profit formula
Profit = Revenue - Cost
Step2: Substitute given polynomials
Revenue = $3x^{2}+4x - 60$, Cost = $3x^{2}-x + 200$. So, Profit=$(3x^{2}+4x - 60)-(3x^{2}-x + 200)$
Step3: Remove parentheses
Profit = $3x^{2}+4x - 60-3x^{2}+x - 200$
Step4: Combine like - terms
$(3x^{2}-3x^{2})+(4x + x)+(-60 - 200)=5x-260$
Answer:
C. $5x - 260$
