Plz help math!!!!!!!!!!!!!!

Here's the problem:

Kelly is making punch for a party. The recipe for punch uses 3 pints of pineapple juice, 5 cups of ginger ale, 1quart of lemonade, and 1 quart of apricot nectar. Kelly says that her recipe will make 20 cups of punch. Is she correct? Please explain how u did it.

Thx

NO - it will only make 19 cups

Convert Everything

3 pints = 6 cups ( 2 cups per pint)
+
5 cups = 5 cups
+
1 quart = 4 cups (4 cups per quart)
+
1 quart = 4 cups (4 cups per quart)

4 cups + 4cups = 8 cups + 5 cups = 13 cups + 6 cups = 19 Cups

Basically covert everything to cups (since that is what your answer is in) and then add together to get a total amount. Which is 19 cups.

1 pint = 2.4019 cups
1 quart = 4.8038 cups
1 cup = 1 cup

3 pints of pineapple juice is hence 3 x 2.4019 cups = 7.2057 cups
1 quart of lemonade + 1 quart of apricot nectar = 4.8038 + 4.8038 = 9.6076 cups
5 cups of ginger ale = 5 cups of ginger ale

Add together 7.2057 + 9.6076 + 5 = 21.833 .
She is wrong it will make 21 and a small one for herself,. It makes enough though :D

First of all I need to say that I'm an American trying to answer this question, from someone using the UK and Ireland site. So maybe I shouldn't even be doing this.

From what I can gather, the sizes of quarts and pints are different between the United States and the United Kingdom. And as far as "cups" go, there seems to be some uncertainty out there. I think "cups" are normally either "US" cups or "Metric" cups.

Since this question was asked on the UK site, we should probably use UK values for quarts and pints when we convert these into cups. So, I think Dom is the only one so far who has done this problem right (more or less).
