r(x) = x2 + 20x + 50 (where x is the number of phones produced per month). The cost of production is given by the function c(x) = 50x + 30. Which function gives the profit earned by the company?

Solve for x in your first equation and plug it in to the 2nd one?!

Would it be -5(2+√2)?

if I told you my revenue was 300 and my cost of production was 100, what is my profit? what did you have to do with those two numbers to get the profit? it's the same except do it with polynomials

First, you need to understand the concepts of REVENUE, COST and PROFIT. Can you define them? They are related through an equation. What is that equation?
AtomicReaper
  • AtomicReaper
Well if your revenue was 300 and your cost was 100, then your profit would be 200.
mathmale
  • mathmale
Yes. Could you share the equation you used to obtain that result, and explain it?

  • AtomicReaper
R= Revenue= 300 C= Cost= 100 P= Profit=? So 300-100=200

On the right track, yes. This question is pretty much the same.

So using that equation, just plug in the equations you have into that one..

Formally, P = R - C. In words, "Profit is Revenue less Costs." What is the formula for revenue? What is the formula for costs? Now, put this info together to obtain a formula for profit.

I got D

well x^2+30x+20

What's that? Label your equations: R(x) = ? C(x) = ? P(x) = ? Once you have P(x) = R(x) - C(x) set up, substitute the algebraic formuls for R and C, do the algebra and write your formula for profit, P(x).
