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?

40x – 30; $2,400
40x – 30; $9,570
70x + 50; $16, 850
70x + 50; $28,800

Option C. 70x + 50; $16, 850

Step-by-step explanation:

Profit = Revenue - Cost

The revenue of the company can be modeled =

The cost of producing the cell phones can be modeled =

Here variable x represents the number of cell phones sold.

Therefore, profit would be

           = 70x + 50

By substituting the number of sold cell phones in place of x.

= 70(240) + 50

= 16,800 + 50

= $16,850

Hence, the answer would be option C.
