Question

a cookie recipe calls for 3 and 1/4 cup of flour the recipe makes three dozen cookies how much flour is needed to make 144 cookies

Answer 1

13 cups

Explanation:

A recipe of cookie requires amount of flour =
`3(1)/(4)` cups

or amount of flour required =
`(13)/(4)` cups

Now 3 dozens of cookies or 36 cookies require flour =
`(13)/(4)` cups

So 1 cookie will require flour =
`(13)/(4* 36)`

Therefore, 144 cookies will require flour =
`(13* 144)/(4* 36)` = 13 cups

13 cups of flour will be required to prepare 144 cookies.
