Answer: The fabric costs $7.60 per yard.
Step-by-step explanation: First we can divide it by 106 then multiply it by 100 to get rid of the 6% sales tax, which now the cost of the stuff is $17.50.

The last stap to this is to divide it by 1 1/4 to get the final cost per yard:
The fabric costs $7.60 per yard.
