Final answer:
After calculating the length of ribbon to create one bow is 16 cm, we find out Emily can make additional 11 bows with the leftover 176 cm of ribbon she has.
Explanation:
The subject of this question is Mathematics and it falls under the Middle School grade category. The question involves the mathematical concept of ratios, specifically, solving word problems using subtraction and division.
Firstly, we need to find out how much ribbon it took to make one bow. As Dawn and Emily are making identical bows, the length of ribbon they both used altogether before having the left-over has to be the same. Hence, we need to find out the remaining amount of ribbon after both girls made their bows.
Dawn used her ribbon to make 12 bows and still had 128 cm left. Emily, on the other hand, made 9 bows and had 176 cm left. By subtracting, we get that 176 cm - 128 cm = 48 cm. This difference shows that making 3 more bows (12-9 bows) required 48 cm of ribbon. Thus, every single bow requires 48 cm / 3 = 16 cm of ribbon.
Finally, to find out how many bows Emily could make with the ribbon she has left, divide her remaining ribbon length by the length required for one bow: 176 cm / 16 cm = 11 bows. So, Emily could create 11 additional bows with the remaining ribbon she has.
