Answer:
The vertex is (0,0)
Step-by-step explanation:
To find the x coordinate of the vertex
x = -b/2a where ax^2 +bx +c
a=1 b=0 c=0
x = -0/2(1) = 0
The y value is found by substituting into the equation
y = (0)^2 =0
The vertex is (0,0)
Total Cost in a day is
![TC= 90 + 12n](https://tex.z-dn.net/?f=TC%3D%2090%20%2B%2012n)
. Profit function is
![P=18n](https://tex.z-dn.net/?f=P%3D18n)
. And the revenue function is
![R = P-TC = 18n-12n-90 = 6n-90](https://tex.z-dn.net/?f=R%20%3D%20P-TC%20%3D%2018n-12n-90%20%3D%206n-90)
. In a day, bookstore must sell at least 15 books, because of 6n-90=0, in order to make profit.
