Final answer:
The correct answer is B. 24 dozen cookies can be made with 9 cups of flour when 3/4 cup of flour makes 2 dozen cookies.
Step-by-step explanation:
To answer the question, first we need to determine how many cookies can be made with 1 cup of flour. We know that 3/4 cup of flour makes 2 dozen cookies. Therefore, one full cup would make ×(2 / (3/4)) = ×(2 / 0.75) = ×(2.666) dozens of cookies, which is 8/3 dozen cookies per cup. Next, to find out how many cookies can be made with 9 cups of flour, we multiply the number of dozens per cup by 9. So, (8/3) dozen per cup × 9 cups = 24 dozens of cookies. Hence, the correct answer is B. 24 dozen cookies.
