Answer:
The maximal number of smothies that Carol can make with the yogurt is 4.
Step-by-step explanation:
Divide the number of cups Carol has by the number of cups needed to make one smoothie.
![1\dfrac{5}{8}:\dfrac{1}{3}=\dfrac{13}{8}\cdot \dfrac{3}{1}=\dfrac{39}{8}=4\dfrac{7}{8}.](https://tex.z-dn.net/?f=1%5Cdfrac%7B5%7D%7B8%7D%3A%5Cdfrac%7B1%7D%7B3%7D%3D%5Cdfrac%7B13%7D%7B8%7D%5Ccdot%20%5Cdfrac%7B3%7D%7B1%7D%3D%5Cdfrac%7B39%7D%7B8%7D%3D4%5Cdfrac%7B7%7D%7B8%7D.)
The maximal number of smothies that Carol can make with the yogurt is 4.
Answer:
vertex = ( -6 , -3 )
focus = ![(-\frac{97}{16} ,-3)](https://tex.z-dn.net/?f=%28-%5Cfrac%7B97%7D%7B16%7D%20%2C-3%29)
axis of symmetry = y = -3
directrix = x = ![-\frac{95}{16}](https://tex.z-dn.net/?f=-%5Cfrac%7B95%7D%7B16%7D)
GRAPH :
Let N be the number of items sold and p the price.
Since the variation is inverse, then the relation between N and p is:
![N=k\dfrac{1}{p}](https://tex.z-dn.net/?f=N%3Dk%5Cdfrac%7B1%7D%7Bp%7D)
For N=20000 and p = $9.5, we get the formula:
![20000=k\dfrac{1}{9.5}\\p=20000\times9.5=190000](https://tex.z-dn.net/?f=20000%3Dk%5Cdfrac%7B1%7D%7B9.5%7D%5C%5Cp%3D20000%5Ctimes9.5%3D190000)
If p = 8.75, then the number of items sold can be computed using the formula:
