Stacy wants to make 100 name tags with ribbons attached to them. each name tag requries 5 centimeter of ribbon. she has 3.25 meters of ribbon. exactly how many more centimeters of ribbon does stacy still need to make 100 name tags

So convert 3.25 meters to centimeters, and you get 325 centimeters.
Now divide 325 by 5 (for each ribbon), and you get 65 name tags.
Therefore, she needs 35 MORE name tags to get to 100.
Multiply 35 by 5 and you get 175 MORE centimeters of ribbon.

Hope this helped!
