Answer:
6 cups
Step-by-step explanation:
Given that B cups of dough divided into 3 equal parts.
So each part will have
[tex]\frac{B}{3}[/tex] cups
Since it is given to double we can expect after doubling available cups in each part wouldbe
[tex]\frac{2B}{3}[/tex]
This is given to equal 4
Equate and solve for B
[tex]\frac{2B}{3}=4\\2B =4*3\\B=6[/tex]
Hence Kitty started with 6 cups of dough
