The slope of the line should be (-8/9). You find this by doing y2-y1/x2-x1.

Answer: 175

Step-by-step explanation:

To find maximum, we need to find the vertex.

The x-value of the vertex is the number of automobiles that should be made and sold. The y-value is the maximum profit.

P(x) = -10x² + 3500x - 66,000

a=-10, b = 3500, c=-66,000

$x=\dfrac{-b}{2a}$

$x=\dfrac{-(3500)}{2(-10)}$

$x = \dfrac{-3500}{-20}$

$x = 175$

BONUS:

The maximum profit is: P(x) = -10(175)² + 3500(175) - 66,000

= -300,625 + 612,500 - 66,000

= 245,875
