Answer:

Step-by-step explanation:

(4 - 18)( x+ 3) (-1)= 8 - 72 +162

An automobile manufacturer can produce up to 300 cars per day. The profit made from the sale of these vehicles can be modeled by

drek231 [11]

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
