Athena is trying to drink more water, so she has been keeping a log of how much water she drinks. two days ago, athena drank 80 ounces of water, in comparison to 76 ounces yesterday. what was the percent of decrease in athena's daily water consumption?

Hello There!

Percentage increase or decrease = difference of values / original value.  x 100
Percentage decrease = 80 - 76/80
80 - 76 = 4
4/80 = 0.05
0.05 x 100 = 5

In short, the decrease in Athena's daily water consumption is 5%.

Hope This Helps You!
Good Luck :)

I would assume the answer would be 10 mm³ since you are asking for volume.

10 mm is wrong because it represents a length, but 10 mm³ is correct because it represents a volume of an object.
