Question

The revenue, in dollars, of a company that makes toy cars can be modeled by the polynomial 3x2 + 4x – 60. The cost, in dollars, of producing the toy cars can be modeled by 3x2 – 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 1

Profit = revenue − cost = (3x^2 + 4x − 60) − (3x^2 − x + 200) = 5x − 260.

Answer: 5x − 260.
