Answer: $30
Explanation:
The mixed number 3 1/4 is the same as the decimal 3.25
If she bought 3.25 yards of fabric at a cost of $26, then the cost per yard is (26)/(3.25) = 8 dollars.
One extra yard costs 8 dollars.
That means an extra 1/2 yard must cost an additional 8/2 = 4 dollars
The total cost $26 updates to $30.
