Answer:
James will get $1.20.
Explanation:
We have been given that James brought 2 gallons of water and Karen brought 1 3/4 gallons of water.
First of all, we will find amount of water per person by dividing 2 gallons plus 1 3/4 (1.75) gallons by 3.



James will keep 1.25 gallons and given 0.75 gallon to Lou.

This means James gave 40% of Lou's water to him, so James will get 60% of $2.

Therefore, James will get $1.20.
