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?

(1 quart = 32 fluid ounces, 1 gallon = 4 quarts)
a. 1 bottle
b. 2 bottles
c.3 bottles
d. 4 bottles

Ok so first we need to find how many fluid ounces all the cups hold in totoal. 
so 25*12=300
So we have 300 ounces in the cups and 300 ounces is around 2.34 gallons. So we need 2.34 gallons to fill all the cups, and one bottle is one gallon, so if we get two bottles we have 2 gallons, which is a little under the amount we need. So we would need to buy 3 bottles (3 gallons) to have enough to drink.

Hope that helpes:) if it dosn't make sense PM me and I can try to explain better :)

The 4L is better. Because if you bought 2 of the 2L then your total would be 5.80.
