Answer:
13 cups
Step-by-step explanation:
A recipe of cookie requires amount of flour = [tex]3\frac{1}{4}[/tex] cups
or amount of flour required = [tex]\frac{13}{4}[/tex] cups
Now 3 dozens of cookies or 36 cookies require flour = [tex]\frac{13}{4}[/tex] cups
So 1 cookie will require flour = [tex]\frac{13}{4\times 36}[/tex]
Therefore, 144 cookies will require flour = [tex]\frac{13\times 144}{4\times 36}[/tex] = 13 cups
13 cups of flour will be required to prepare 144 cookies.
