Answer:
n = ( 40 - m )
Explanation:
On a particular day, Ricardo drank a total of 40 fluid ounces of water.
If he drank m fluid ounces of water in the morning of that day, then the number of fluid ounces of water he drank the rest of the day is given by (40 - m) fluid ounces.
If n represents the number of fluid ounces water that he drank the rest of the day, then we can write the equation as
n = ( 40 - m )
