Answer:
11.25 dozens.
Step-by-step explanation:
We have been given a table of ingredients used for making 2 dozens of muffins.
First of all, we will find amount of flour used to make one dozen of muffins as:
\(\text{Amount of flour used to make one dozen muffins}=\frac{4.5\text{ cup}}{\text{2 dozens}}\)
\(\text{Amount of flour used to make one dozen muffins}=\frac{2.25\text{ cup}}{\text{dozen}}\)
\(\text{Amount of flour used to make 5 dozen muffins}=\text{ 5 dozens}\times \frac{2.25\text{ cup}}{\text{dozen}}\)
\(\text{Amount of flour used to make 5 dozen muffins}=5\times 2.25\text{ cup}\)
\(\text{Amount of flour used to make 5 dozen muffins}=11.25\text{ cup}\)
Therefore, 11.25 cups of flour are needed to make 5 dozens of muffins.
