An area for planting crops is given by:
A = 800 + 20x - 1/2x^2
Find the value of x which the area is a maximum
recall that the vertex of a parabola is at x = -b/2a
In this problem, that is
x = -20/-1 = 20
A = 800 + 20x - 1/2x^2
Find the value of x which the area is a maximum
In this problem, that is
x = -20/-1 = 20
