The price of an item is given by p=2x^2 - 100
Find the polynomial that represents the revenue generated from the sale of x items.
;
They don't want to solve it, just write an equation that will give you the amt of revenue for a given number of items sold (x)
:
They tell you two things
Price (p) = 2x^2 - 100
and
The number of items is given as the value of x
:
We know that revenue (R) = number of items sold (x) * the price (p), therefore:
R = x * (2x^2 - 100)
:
Multiply what's inside the brackets and you have:
R = 2x^3 - 100x; this is what they want
