Answer:15
Step-by-step explanation:
Given
Craftsman sell 10 Jewelry set for $500 each
For each additional set he will decrease the price by $ 25
Suppose he sells n set over 10 set
Earning![=\text{Price of each set}\times \text{no of set}](https://tex.z-dn.net/?f=%3D%5Ctext%7BPrice%20of%20each%20set%7D%5Ctimes%20%5Ctext%7Bno%20of%20set%7D)
Earning ![=(500-25n)(10+n)](https://tex.z-dn.net/?f=%3D%28500-25n%29%2810%2Bn%29)
![E=5000+500n-25n^2-250n](https://tex.z-dn.net/?f=E%3D5000%2B500n-25n%5E2-250n)
differentiate to get the maximum value
![\frac{dE}{dn}=-50n+250](https://tex.z-dn.net/?f=%5Cfrac%7BdE%7D%7Bdn%7D%3D-50n%2B250)
Equate
to get maximum value
![-50n+250=0](https://tex.z-dn.net/?f=-50n%2B250%3D0)
![n=\frac{250}{50}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B250%7D%7B50%7D)
![n=5](https://tex.z-dn.net/?f=n%3D5)
Thus must sell 5 extra set to maximize its earnings.
Well all u have to do is minus -6 from 23 so 23-6 is 17. Then all u have to do is add 0+17 so ur answer is the temperature changed 17 F
Answer:
k=1
Step-by-step explanation:
Since the coefficient of
is 1, that is what you put for k
A)your equation for t-mobile would be
y=20x+100
Topar equation
y=30x
B) you’d set the two equation equal to each other
20x+100=30x
giving you the answer x=10
C) when x>13
D) when x<14
i’m a bit iffy on the last two but that’s the conclusion i came to
