Question 10 • FL-1200700-Mathematics for College Algebra MIS

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.

Answer
A
3x – 260
B
3x + 140
C
5x – 260
D
5x + 140

Explanation

Profit equals revenue minus cost. Subtract the cost polynomial from the revenue polynomial: (3x² + 4x − 60) − (3x² − x + 200). The 3x² terms cancel, and combining the remaining terms gives 5x − 260, so the profit is represented by choice C.
