At a local print shop, 18 copies can be made for $3. At this rate, how much would it cost to make 72 copies?

12$

Step-by-step explanation:

In order to find how much it would cost we have to find how many times to add the 3 dollar cost to the 18 out of 72 copies, just divide 72 by 18 to get 4 then 4*3=12$

I believe that 12 dollars is the answer.

Step-by-step explanation

72 is 18 multiplied by 4, and if you know that 3 dollars is for 18 copies. Then, multiply 3 by 4 since you multiplied 18 and 4 which gets you 12 dollars.
