> Factor the expression for the revenue
We are given that the revenue is the product of price and number of units sold = x p. Given the equation of revenue we factor it:
R = 800 x – 0.25 x^2
Take out x from the equation:
R = x (800 – 0.25 x)
We see that this is now in the form x p
> Determine an expression for the price in terms of x
From the factored equation we can say that the price in terms of x is:
p = 800 – 0.25 x
