Varvara68 [4.7K]

Answer:

n = ( 40 - m )

Step-by-step 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 )

Therefore, the above equation can be used to find n. (Answer)
