Answer: 175
<u>Step-by-step explanation:</u>
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. <em>The y-value is the maximum profit.</em>
P(x) = -10x² + 3500x - 66,000
a=-10, b = 3500, c=-66,000




<u>BONUS:</u>
The maximum profit is: P(x) = -10(175)² + 3500(175) - 66,000
= -300,625 + 612,500 - 66,000
= 245,875
<h3>solution:-</h3>
<u>We </u><u>have</u><u>,</u>
= -6(3x - 2/3)
= -6(3x × 3 - 2)/3
= -6(9x - 2)/3
= -2(9x - 2)
= (-18x + 4)
<u>Your </u><u>answer</u><u> will</u><u> be</u><u> </u><u>option</u><u> number</u><u> </u><u>4</u><u>.</u>
Answer: 60 percent decrease
===========================================
Change in price = new - old = 100 - 250 = -150
The negative change means the price has gone down
Divide this change in price over the original 250 and convert to percent form
(change in price)/(original price) = -150/250 = -0.60
which converts to -60%
The negative percent change in price indicates a price decrease
So the price goes down by 60% meaning that it lost 60% of its value
Note how 60% of 250 is 0.60*250 = 150 which was the change in price computed earlier.
