The vertex is at (500, 10)
500 units sold 10 million dollar revenue, since written in vertex form.
can expand this to R(x)=-x^2+1000x-249990
vertex is -b/2a=1000/2=500.
The point is that you can look at the problem and write the answer without expanding the formula. The vertex is the maximum for a negative quadratic, and vertex form gives you both the x and y values.
