Debbie needs to fill juice cups for her little brothers birthday party. there are 20 juice cups and each cup holds 10 fluid ounces. the juice comes in 1 gallon bottles. how many 1 gallon bottles of juice will debbie need to purches?

1 bottle
2 bottles
3 bottles
4 bottles

Answer 1

so
8 ounce=1 cup
2 cups=1pint
2 pints=1 quart
4 quarts=1 gallon
128 ounces in 1 gallon

so she needs to get 10 times 20 ounces (200 oz) so
she will need to purchase (200/128) 1.5625 gallons

normally you cannot purchase a fraction of a gallon so she sill have to purchase 2 gallons
