Final answer:
To find the total amount of flour Kayla started with, we can set up an equation using the information given and solve for x which gives us 12 cups.
Step-by-step explanation:
To find the total amount of flour she started with, we can set up an equation using the information given.
Let x be the total amount of flour.
We know that 9 cups is equal to 3/4 of the total amount, so we can write the equation:
9 = (3/4)x
To solve for x, we can multiply both sides of the equation by (4/3):
(4/3) * 9 = x
x = 12
Therefore, the total amount of flour Kayla started with is 12 cups.
