Math Help - Revenue Function

1. Revenue Function

I dont understand this question. Can you please tell me how to do the question, and help me with doing it?

The demand function for snack cakes at a large bakery is given by the function $p(x) = \frac{15}{2x^2+11x+5}$. The $x$-units are given in thousands of cakes, and the price per snack cake, $p(x)$, is in dollars.

a) Find the revenue function for the cakes

b) Estimate the marginal revenue for $x=0.750$. What is the marginal revenue for $x=2.00$?

The revenue function is R(x) = quantity * price = x * p(x).

Marginal Revenue refers to R'(x), the first derivative of Revenue.

Good luck!

3. What do you mean by "R(x) = quantity * price = x * p(x)." ???

4. Sure:

revenue = price times quantity

Example:
You sell 20 cds at ten dollars each:

x = quantity = 20 cds
p(x) = \$10
R(x) = revenue = x * p(x) = 20 * 10 = 200

5. Thank you, but for some reason, the answer is soppsoe to be $
R(x) = \frac{15}{2x^2+11x+5}
$

That is what it says in the Answers for that question
