Final answer:
The waitress pours 96 fluid ounces of orange juice when she pours 3/4 of a gallon, using the conversion of 1 gallon equals 128 fluid ounces.
Step-by-step explanation:
To solve the question of how much orange juice is poured by the waitress in fluid ounces, we first need to know the conversion between gallons and fluid ounces. One gallon equates to 128 fluid ounces. Therefore, if the waitress pours 3/4 of a gallon of orange juice, we multiply 3/4 by 128 fluid ounces to get the total amount poured.
Calculation:
(3/4) gallon * 128 fluid ounces/gallon = 96 fluid ounces
Thus, the waitress pours 96 fluid ounces of orange juice.
