So we will be using dimensional analysis to solve it as such:
![\frac{23843\ kL}{1}*\frac{1000\ L}{1\ kL}*\frac{1\ Gal}{3.79\ L}=\frac{23843000}{3.79}=6291029.02\ Gallons](https://tex.z-dn.net/?f=%20%5Cfrac%7B23843%5C%20kL%7D%7B1%7D%2A%5Cfrac%7B1000%5C%20L%7D%7B1%5C%20kL%7D%2A%5Cfrac%7B1%5C%20Gal%7D%7B3.79%5C%20L%7D%3D%5Cfrac%7B23843000%7D%7B3.79%7D%3D6291029.02%5C%20Gallons%20)
In short, 23,843 kL is 6,291,029.02 (6,291,029 rounded to the whole gallon) gallons.
I believe the answer is 180, I got the answer by dividing 15 by 85 and taking the product and multiply it by thirty, which isn't the usual way of answering the question but it still gets you the answer.
