Answer:
900 Fluid Ounces
Explanation:
First add the number of people drinking the ounces. That would be adding the number of teachers and students.
40 + 94 = 134
It would 134 people.
Then multiply the number of people with the number of ounces in order to find an estimate of how much fluid ounces would be needed.
![134*6(2)/(3) = 892.44](https://img.qammunity.org/2020/formulas/mathematics/high-school/t7ld62r65gph3k3o968d13w6904j4s4ns1.png)
Since it's an estimate, we can round to the nearest hundred to make sure there is enough.
(approximately)
The answer would be 900 fluid ounces.
