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 :)

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
