Answer:
108 tablespoons of cinnamon
This is a simple math problem that can be solved by using proportions.
First, we need to find out how much sugar Laura used in total. She used 9 packets of sugar, which contain 4 tablespoons of sugar each. So, to find the total amount of sugar, we multiply 9 by 4 and get 36 tablespoons.
Next, we need to find out how much cinnamon Laura needs to use. The recipe says she needs to use three times as much cinnamon than sugar. So, to find the amount of cinnamon, we multiply 36 by 3 and get 108 tablespoons.
That's a lot of cinnamon! Laura must really like spicy cookies. Or maybe she's trying to prank someone with her cookies. Either way, the answer is 108 tablespoons of cinnamon.
