2001 gallons used in 5 days, so the average for one day is 2001/5=400.2 gallons.
Answer:
27 gallons is the capacity of the tank.
Step-by-step explanation:
Let the capacity of the tank be x gallons.
Initial tank was filled = ![\frac{1}{7}x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7Dx%20)
After travelling tank was found to have = ![\frac{1}{9}x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7Dx)
24 gallons of gasoline was added to fill the tank completely.
![x=+\frac{1}{9}x+24](https://tex.z-dn.net/?f=x%3D%2B%5Cfrac%7B1%7D%7B9%7Dx%2B24)
![x-\frac{1}{9}x=24](https://tex.z-dn.net/?f=x-%5Cfrac%7B1%7D%7B9%7Dx%3D24)
![\frac{9x-1x}{9}=24](https://tex.z-dn.net/?f=%5Cfrac%7B9x-1x%7D%7B9%7D%3D24)
![\frac{8x}{9}=24](https://tex.z-dn.net/?f=%5Cfrac%7B8x%7D%7B9%7D%3D24)
![x=\frac{24\times 9}{8}=27](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B24%5Ctimes%209%7D%7B8%7D%3D27)
27 gallons is the capacity of the tank.
