Question

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones can be modeled by the polynomial 2x2 + 55x + 10. The cost, in dollars, of producing the cell phones can be modeled by 2x2 – 15x – 40. The variable x represents the number of cell phones sold.
What expression represents the profit, and what is the profit if 240 cell phones are sold?

A)40x – 30; $2,400
B)40x – 30; $9,570
C)70x + 50; $16, 850
D)70x + 50; $28,800

Answer 2

Profit = Revenue - Cost
P = (2x² + 55x + 10) - (2x² - 15x - 40)
P = 70x + 50

Profit with 240 cell phones = 70(240) + 50
= 16800 + 50 = 16,850

In short, Your Answer would be Option C

Hope this helps!
