Answer 1

b. $70.25

Explanation:

• Given:, The fabric cost per yard = $6.69.

,

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

Liz needed 10½ yards of the fabric and a yard of the fabric costs $6.69.

To find the total cost, multiply the cost per yard by the total yards needed.

Therefore:

`\begin{gathered} \text{Total Cost}=10(1)/(2)*6.69 \\ =(10+(1)/(2))*6.69 \\ =(10*6.69)+((1)/(2)*6.69) \\ =66.9+3.35 \\ =\$70.25 \end{gathered}`

Her total cost was $70.25 (Option B is correct).
