Answer:
9 scarves.
Step-by-step explanation:
We have been given that the number N of scarves Ariana can make is inversely proportional to the area A of each scarf.
We know that equation of two inversely proportional quantities in in form , where, k is constant of variation and y is inversely proportional to x.
Let us find constant of variation using our given information.
Now, we will substitute in our equation to solve for N.
Therefore, Ariana can make 9 scarves.
