Answer:

  (2c³ -20c² -10c) -(c² -40c +100)

Step-by-step explanation:

<u>Profit</u>

For a problem involving cost, revenue, and profit, you are expected to know that <em>profit is the difference between revenue and cost</em>. That is, if it costs you $2 to make a necklace you sell for $10, your profit is $10 -2 = $8.

<u>Problem</u>

The problem gives you polynomial expressions for revenue and cost, and asks you to combine them to make an expression for profit. In this first part, we simply show <em>how</em> we will combine them. (We presume a later part of the question will ask you to simplify the result.)

  profit = revenue - cost

Substituting the given expressions, we have ...

  profit = (2c³ -20c² -10c) -(c² -40c +100) . . . . . matches last choice
