,• To find:, The total cost for 10½ yards.

To find the total cost, multiply the cost per yard by the total yards needed.
Therefore:
[tex]\begin{gathered} \text{Total Cost}=10\frac{1}{2}\times6.69 \\ =(10+\frac{1}{2})\times6.69 \\ =(10\times6.69)+(\frac{1}{2}\times6.69) \\ =66.9+3.35 \\ =\$70.25 \end{gathered}[/tex]Her total cost was $70.25 (Option B is correct).
