Evaluate the following expressions. Give economic interpretations for each. (a) C(175) (b) C(175)-C(150) (c) C(175)- C(150) divided by 175-150

What's this?

OpenStudy (anonymous):

I don't know I am extremely confused on it.

OpenStudy (anonymous):

So is everybody else...

OpenStudy (anonymous):

What does it mean?

OpenStudy (anonymous):

What is C?

OpenStudy (anonymous):

When u figure out what it means, post it agian....

OpenStudy (anonymous):

It just doesn't make any since to me. It's the only information the book gives me for my MAT 150 class and it is 1.4 Formulas for Linear functions in my book.

OpenStudy (anonymous):

C is a variable that they are using.

OpenStudy (anonymous):

Then why is it expressed a as a function?

OpenStudy (anonymous):

Well C is still a variable because it is a letter but it's a function problem I just have no clue how to work it out.

OpenStudy (anonymous):

C(x) must have some formula or rule to go with it, the question is meaningless without it.

OpenStudy (anonymous):

I'm looking at it but give me a second because I'm not seeing anything else on it

OpenStudy (anonymous):

I know some things in this section have to do with Rate of Change but I doesnt look like that is part of the problem

OpenStudy (anonymous):

C(150) means (usually) evaluate C (the function C) at 150.. So u need a function (or some other explanation of what C(150) might mean).

OpenStudy (anonymous):

Okay thank you. Could you try one of my other questions I can go get some help from the Math lab on this problem.
