Question 242386
Let c = cartons

3864/c = 0.4/1

Can you solve for c now?

========================

I received your reply.

Let c = cartons 

3864/c = 0.4/1 

We cross-multiply to find c.
 
c times 0.4 = 3864 times 1
 
0.4c = 3864
 
We now divide both sides by 0.4 to find c, which is our cartons.
 
c = 3864/0.4
 
c = 9660 cartons
