Answer:
80 cups of juice
Explanation:
From the question,we understand that Dashaun brings five 1 gallons of juice to serve during parents night at his school if the cups he is using for drinks can hold 8 fluid ounces how many drinks can dashuan serve.
Since both are units for measuring volume of a liquid(gallons and ounces),we need to know how many ounces makes a galoom which is
128 ounces 1 gallon
Since Dashaun brought five 1 gallons,in ounces it means that he brought 128 × 5 = 640 fluid ounces of juice to be served.
And if eight ounces of juice fills a cup,then the number of cups served by Dashaun to the guests is
640/8 = 80 cups of juice
