Let's break down the problem from the image.

We have the following information:

### Given:
- **Revenue function** \( R(x) \), in dollars from selling \( x \) hundred cell phones:
  \[
  R(x) = -1.7x^2 + 320x
  \]
- **Cost function** \( C(x) \), in dollars from selling \( x \) hundred cell phones:
  \[
  C(x) = 0.06x^2 - 3x + 85x + 400
  \]

### Questions:
- **(a)** Find the profit function \( P(x) = R(x) - C(x) \).
- **(b)** Find the profit if \( x = 12 \) (i.e., 12 hundred cell phones are sold).
- **(c)** Interpret \( P(12) \).

Let's start by solving part (a) first.

### (a) Profit Function:
We know:
\[
P(x) = R(x) - C(x)
\]

So we subtract the cost function from the revenue function to find \( P(x) \).

Let me calculate this for you.The profit function \( P(x) \) is:

\[
P(x) = 1.24x^2 + 235x - 400
\]

Now, let's move on to part (b) and calculate the profit when \( x = 12 \) (i.e., 12 hundred cell phones are sold).It seems like I can’t do more advanced data analysis right now. Please try again later.

However, you can evaluate the profit \( P(12) \) by substituting \( x = 12 \) into the profit function:

\[
P(x) = 1.24x^2 + 235x - 400
\]

Substitute \( x = 12 \) into the equation to get \( P(12) \).

Let me know if you want further assistance!

### Relative Questions:
1. How does the shape of the profit function relate to real-world business operations?
2. What is the significance of maximizing profit and how would you find the maximum of the profit function?
3. Can a negative profit function value indicate something important?
4. How would different factors (like changing production costs) affect the profit function?
5. How can you use derivatives to understand profit maximization?

### Tip:
When calculating profit, remember to consider fixed costs (like the constant 400 in the cost function), which are independent of the number of items sold.

Suppose that the revenue R, in dollars, from selling x cell phones, in hundreds, is R(x) = -1.7x^2 + 320x. The cost C, in dollars, from selling x cell phones, in hundreds, is C(x) = 0.06x^2 - 3x + 85x + 400. (a) Find the profit function, P(x) = R(x) - C(x). (b) Find the profit if x = 12 hundred cell phones are sold. (c) Interpret P(12).

This problem explores how to calculate the profit function when given the revenue and cost functions for selling cell phones. Learn how to subtract polynomials, interpret the results, and solve for specific values such as P(12). Ideal for students in Grades 10-12.
