Consumer demand A movie studio is releasing a new DVD, and the studio estimates that if the DVD is priced at $19.99, it will sell 6.68 million copies, whereas if it is priced at $15.99, it will sell 11.27 million copies. If f is a linear function that gives the number of copies sold (in millions) at a given price, what is the slope of f ? What does it represent in this context?

What do YOU think ?
While we're happy to help we're not going to do all the work for you.

Okay. I may have not made myself clear.

I'm done first one, but I don't know the second question: "What does it represent in this context?" I don't know how to answer this question. Could you please tell me the hints.

What does the slope tell you ?

The slope is a rate of change. The slope is 6.68 and 11.27 in my answer.

I think you may need to look at the chapter in your text book again.
These type of slopes can tell you alot of things concerning consumer demand..

Okay! Thank you :)
