Question

Earl needs to fill juice cups for his little brother's birthday party. There are 25 juice cups and each juice cup holds 12 fluid ounces. The juice comes in 1-gallon bottles. How many 1-gallon bottles of juice will Earl need to purchase?

Answer 1

1 gallon = 128 fluid ounces

25*12 = 300 total fluid ounces needed

300/128 = 2.34 gallons are needed

 so he will need to buy 3 1 gallon bottles.
