CORRECT QUESTION:
Kelly is having a party. She wants to make punch and have everything set up before the guests arrive at 1:30.
The recipe for punch uses 3 pints of pineapple juice, 5 cups of ginger ale, ¼ gallon of lemonade, and 1 quart of apricot nectar. Kelly says her recipe will make 20 cups of punch. Is Kelly correct?
Answer:
To find out, if Kelly is correct, we need to convert all the values to cups.
3 pints of pineapple = ( 1 pint = 2 cups) ∴ 3 pints = 3 × 2 = 6 cups
ginger ale is in cups already = 5 cups.
¼ gallon of lemonade, = ( 1 gallon = 16 cups) ∴ ¼ gallon = ¼ × 16 = 4 cups
1 quart of apricot nectar = (1 quart = 4 cups) ∴ 1 quart = 1 × 4 = 4 cups.
summation of all the converted values gives,
6 + 5 + 4 + 4 = 19 cups.
Kelly is wrong, Her recipe will make 19 cups.
