Answer: There is [tex]2\frac{11}{14}\ cups[/tex] needed to make every dozen of muffins.
Explanation:
Since we have given that
Number of cups is needed to make 112 dozen muffins = 312
We need to calculate number of cups is required to make every dozen muffins.
For this case, we will use "Unitary method " .
So,
Number of cups is needed to make every dozen muffins is given by
[tex]\frac{312}{112}=\frac{39}{28}=2\frac{11}{14}\ cups[/tex]
Hence, there is [tex]2\frac{11}{14}\ cups[/tex] needed to make every dozen of muffins.
