Let’s define the variable: x = number of units produced

Setting the velocity equal to zero:

A ball is thrown upward from the ground with an initial velocity of 20 m/s. The height of the ball above the ground is given by the equation:

\[x = - rac{b}{2a} = - rac{40}{2(-2)} = 10\]

So, the company should produce 10 units to maximize profit.
