Jobisdone [24]
The maximum profit is the y-coordinate of the vertex of the parabola represented by the equation.

P(c)=-20c^2+320c+5120 \\ \\&#10;a=-20 \\&#10;b=320 \\ \\&#10;\hbox{the vertex } (h,k): \\&#10;h=\frac{-b}{2a}=\frac{-320}{2 \times (-20)}=\frac{-320}{-40}=8 \\&#10;k=f(h)=f(8)=-20 \times 8^2+320 \times 8+5120= \\&#10;=-1280+2560+5120=6400

The maximum value is 6400, but the profit is given in hundreds of dollars, so multiply the value by 100.

The maximum profit the company can make is $640,000.
