Certainly! To find the total cost, you can multiply the number of pairs of butterfly wings by the amount of fabric per pair, and then multiply that by the cost per yard of fabric.
Let's denote:
- Number of pairs of butterfly wings = 13
- Amount of fabric per pair = \(\frac{3}{4}\) yards
- Cost per yard of fabric = $8
The expression for the total cost (\(C\)) would be:
\[ C = 13 \times \left(\frac{3}{4}\) yards\right) \times $8 \]
Now, let's simplify this expression:
\[ C = 13 \times \left(\frac{3}{4}\right) \times 8 \]
\[ C = 13 \times \frac{3}{4} \times 8 \]
\[ C = \frac{39}{4} \times 8 \]
\[ C = \frac{39 \times 8}{4} \]
\[ C = \frac{312}{4} \]
\[ C = 78 \]
Therefore, the total cost for the fabric is $78.
