Answer:
4320 units quantities were demanded
Step-by-step explanation:
Given:
![p = 90 (5) - \frac{q}{10}](https://tex.z-dn.net/?f=p%20%3D%2090%20%285%29%20-%20%5Cfrac%7Bq%7D%7B10%7D)
Required:
The units demanded when price = 18.00
This implies that:
![p = 18.00](https://tex.z-dn.net/?f=p%20%3D%2018.00)
So, we have:
![p = 90 (5) - \frac{q}{10}](https://tex.z-dn.net/?f=p%20%3D%2090%20%285%29%20-%20%5Cfrac%7Bq%7D%7B10%7D)
![18.00 = 90(5) - \frac{q}{10}](https://tex.z-dn.net/?f=18.00%20%3D%2090%285%29%20-%20%5Cfrac%7Bq%7D%7B10%7D)
Open bracket
![18.00 = 450 - \frac{q}{10}](https://tex.z-dn.net/?f=18.00%20%3D%20450%20-%20%5Cfrac%7Bq%7D%7B10%7D)
Collect like terms
![\frac{q}{10} = 450 - 18.00](https://tex.z-dn.net/?f=%5Cfrac%7Bq%7D%7B10%7D%20%3D%20450%20-%2018.00)
![\frac{q}{10} = 432](https://tex.z-dn.net/?f=%5Cfrac%7Bq%7D%7B10%7D%20%3D%20432)
Solve for q
![q = 432 *10](https://tex.z-dn.net/?f=q%20%3D%20432%20%2A10)
![q = 4320](https://tex.z-dn.net/?f=q%20%3D%204320)
Answer:
A.
Step-by-step explanation:
idk how to explain it. all you need to do is look at the graph..... every point is (x,y). x is where it is horizontally and y is vertically
