To find out how much more flour Jana needs, we need to add the amount of flour needed for the pie crust and cookies and subtract it from the amount of flour she already has.
The total amount of flour needed is 5 1/4 + 2 5/8 = 15/4 + 21/8 = 30/8 + 21/8 = 51/8 cups.
Subtracting the amount of flour Jana already has (3 3/4 cups) from the total amount needed (51/8 cups) gives us: 51/8 - 15/8 = 36/8 = 9/2 = 4 1/2 cups.
Therefore, Jana needs 4 1/2 additional cups of flour. The correct answer is A. 4 1/2 cups.
The total amount of flour needed is 5 1/4 + 2 5/8 = 15/4 + 21/8 = 30/8 + 21/8 = 51/8 cups.
