Answer: 1 cup of flour will be left.
Step-by-step explanation:
A bakes started with quantity of flour =12 cups
As she had [tex]9\frac{1}{4}[/tex] cups of flour left after the first bunch of batter
Thus, the quantity she use to make first batter=[tex]12-9\frac{1}{4}[/tex]
[tex]12-\frac{37}{4}=\frac{48-37}{4}=\frac{11}{4}\text(cups)[/tex]
Since, she made she had [tex]6\frac{1}{2}[/tex] cups of flour left after the second bunch of batter
Thus, the quantity she use to make first batter=[tex]9\frac{1}{4}-6\frac{1}{2}[/tex]
[tex]\frac{37}{4}-\frac{13}{2}=\frac{37-26}{4}=\frac{11}{4}\text(cups)[/tex]
Thus, she use [tex]\frac{11}{4}\text(cups)[/tex] for each batter.
Flour used in making 2 more batter=[tex]2\times\frac{11}{4}\text(cups)[/tex]
[tex]=\frac{11}{2}\ cups[/tex]
Thus, Cups of flour left=[tex]6\frac{1}{2}-\frac{11}{2}[/tex]
[tex]=\frac{13}{2}-\frac{11}{2}=\frac{2}{2}=1\ cup[/tex]
