Suppose a company's revenue R (in dollars) from the sale of x units of its product is given by R = 260x. Suppose further that th
Arada [10]

Answer:

C(x) = R(x) - P(x)

C(x) = 260x - P(x)

Step-by-step explanation:

I think some information is missing in the question. However, symbolically, the answer for Total Cost (C(x)) = 260x - P(x), where P(x) is the profit.

Basically, we derived that from:

P(x) = C(x) - R(x).,

By making C(x) subject of formula, we have:

C(x) = R(x) - P(x)

Since, we only know the value of R = 260x, then, we have;

                            C(x) = 260x - P(x)

I need help on the question that are circled

That is way too much questions for one sitting. If you really struggle that much, download this app called photomath. You take a picture of one of the questions and then it instantly solves it and shows the work so you know how to do it.

For 16-25 however, you would need to rewrite your questions on a blank piece of paper with the variables substituted in. So let's say:

a + b² - (c-2).

You would need to rewrite it as the following in order for the app to solve it.

12 + 9² - (4 -2)
