By performing a change of units, we will see that the amount of water left in the can is 3 cups.

How many cups of water are left in the can?

We know that the can originally has 8 cups of water.

Then, you use 4 fluid ounces into each of 10 plants, then the amount used is:

40 fluid ounces.

Now we need to do a change of units.

8 fluid ounce = 1 cup.

1 = (1 cup/ 8 fluid ounces)

Then we can rewrite:

40 fluid ounces = 40 fluid ounces*(1 cup/ 8 fluid ounces) = 5 cups.

This means that lee used 5 cups out of the 8 in the can, so the amount of water left is:

8 cups - 5 cups = 3 cups.
