Part A
There are 2 cups in a pint, so 2 x 3 = 6
Plus 5 cups,
1 quart is equal to 1/4 of a gallon, and there are 4 cups in a gallon,
and another quart is 4 more cups,
so add all of the cups together:
6 + 5 + 4 + 4 = 19
Kelly is incorrect, because I added all of the cups together and I got 19.
Part B
Since 4 cups fit in a quart, and she has 4 quarts, her quarts only hold 16 cups, which isn't enough, because there are 19 cups.
Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)
