Quadratic equation

Question

If a manufacturer can produce a certain item for $7 and sell the item for x dollars, the profit per item will be x-7 dollars. If it is then estimated that consumers will buy 25-x items per month, the total profit will be:

Toral profit=(number of items sold)(profit per item)=(25-x)(x-7)

Answer 1

Using the information provided, FOIL the (25-x)(x-7) to get a polynomial. You will then use that information to calculate an answer using the Quadratic Formula

the number before x² is your A value

the number before x is your B value

and the number with no x is your C value

Answer 2

cost $7 ea

price=x

profit=x-7

sold (25-x)/month

Without a price nobody knows what the profit is.
