Question

Don’t understand that problem

Answer 1

Answer:

  (2c³ -20c² -10c) -(c² -40c +100)

Step-by-step explanation:

Profit

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

Problem

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 how 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
