Ursula bought 9 dozen rolls of first aid tape for the health office. the rolls were divide equally into 4 boxes. how many rolls are in each box?

We know that 12 equals one dozen. It is not asking for a dozen, but for 9 dozen. So, we need to multiply 9 by 12. 9*12 = 108. 

It says the rolls of first aid tape were divided equally into 4 boxes. We need to divide these 108 rolls into 4 equal groups, since that is what took place in the problem. So, we divide 108 by 4. 
108/4 = 27. There are 27 rolls in each box. 

Ithink the answer is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
