Mary is baking a cake. The recipe calls for 24 cups of sugar and 29 cups of flour. She already put in 2 cups of flour. How many more cups of flour than cups of sugar does she need to add now?
First, we need to figure out how many cups of sugar she has left to add. We know she's already put in 2 cups of flour, and the recipe calls for a total of 29 cups of flour. So she has 29 - 2 = 27 cups of flour left to add. 

Next, we need to figure out how many cups of sugar she has left to add. We know she's already put in 2 cups of sugar, and the recipe calls for a total of 24 cups of sugar. So she has 24 - 2 = 22 cups of sugar left to add. 

Now we can compare the two numbers: she has 27 cups of flour left to add, and 22 cups of sugar left to add. So she needs to add 27 - 22 = 5 more cups of flour than she needs to add sugar.
