Given:
The cost to install x number of central air conditioning units for a company is given by the function
![C(x)=\dfrac{4000x+1300}{3}](https://tex.z-dn.net/?f=C%28x%29%3D%5Cdfrac%7B4000x%2B1300%7D%7B3%7D)
To find:
The cost to install 45 air conditioners.
Solution:
We have,
![C(x)=\dfrac{4000x+1300}{3}](https://tex.z-dn.net/?f=C%28x%29%3D%5Cdfrac%7B4000x%2B1300%7D%7B3%7D)
Putting x=45, we get
![C(45)=\dfrac{4000(45)+1300}{3}](https://tex.z-dn.net/?f=C%2845%29%3D%5Cdfrac%7B4000%2845%29%2B1300%7D%7B3%7D)
![C(45)=\dfrac{180000+1300}{3}](https://tex.z-dn.net/?f=C%2845%29%3D%5Cdfrac%7B180000%2B1300%7D%7B3%7D)
![C(45)=\dfrac{181300}{3}](https://tex.z-dn.net/?f=C%2845%29%3D%5Cdfrac%7B181300%7D%7B3%7D)
![C(45)=60433.3333...](https://tex.z-dn.net/?f=C%2845%29%3D60433.3333...)
![C(45)\approx 60433.33](https://tex.z-dn.net/?f=C%2845%29%5Capprox%2060433.33)
Therefore, the cost to install 45 air conditioners is $60433.33.
