So we need to find the inequality, Simple!
So we only have 5 dollars. That we cannot change.
But the snadwich, however, we can change how much we buy. But this problem is asking us how many we can buy. So that is an x. So far, we have 2.25x.
Then we have to use the inequality sign 'less than or equal to' because we can buy less or equal to 5 dollars.
So the equation is
Then we solve by isolating the x. We divide 2.25 both sides then we get

So we will be using dimensional analysis to solve it as such:
In short, 23,843 kL is 6,291,029.02 (6,291,029 rounded to the whole gallon) gallons.
