Answer:
$7.20 will be added
Step-by-step explanation:
Multiply 72 by 1.10
72 x 1.10=79.20
Subtract that by 72
79.20-72=7.20
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.
Next, we subtract 8 from this to represent the clothing pattern cost. Now it is $9.50.
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. Hope this helps!
