Question

7. You are trying to sell a product. If you set
the price at x dollars, your profit is
P(x)=-x2+30x-100.
What price maximizes your profit?
8. You are going to renovate your store. If you
use fewer workers, then it costs less money to
do the work, but you lose more revenue while
the store is closed. Suppose that when you
use x workers, it costs 1000+40×12 to do the
work and you lose 1000x-12 in revenue. Then
the total cost of the project is
C(x)=1000+40×12+1000x-12.
How many workers should you use if you
want to minimize the cost of the project?​

    Step-by-step explanation:

    7. profit,

    =x^2+30x-1000=0

    =x^2+50x-20x-1000=0

    =x(x+50)-20(x+50)=0

    =(x-20)(x+50)=0

    =x-20=0

    =x=20

    =x+50=0

    =x=-50

    maximum profit = 20 dollars●●●●●●●●
