: Given the price-demand function:
: p(x) = 1500 - 20x 1 : a) Give the companies revenue....
: I'm lost...I believe x is the price per item....is 1500 the # of items sold?
Carol,
Can you find a reference in your textbook?
I would guess that p(x) is the price per item (just from the "p")
and that x is the number of items.
If that's true, then Revenue is: R(x) = x*p(x).
Get it? ("Number of apples" times "Price per apple")
Don't be insulted - sometimes "baby talk" makes things clearer. (Works for me!)
