The demand equation for a product is p = 20 − 0.0001x, where p is the price per unit and x is the number of units sold. The total revenue for selling x units is Revenue = xp = x(20 − 0.0001x). How many units must be sold to produce a revenue of $1,000,000? x = ________ units.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
