Greetings!
[tex]3 \frac{1}{4} /3\frac{1}{4}=1 [/tex]
Therfore to find the cost for unit, we must divide the cost by:
[tex]3 \frac{1}{4}[/tex]
[tex]=13/3\frac{1}{4}[/tex]
Simplify.
[tex]=\frac{13}{1} /3\frac{1}{4}[/tex]
Convert mixed number into improper fraction.
[tex]=\frac{13}{1} /\frac{13}{4}[/tex]
Simplify.
[tex]=\frac{13}{1}*\frac{4}{13}[/tex]
[tex]=\frac{52}{13}[/tex]
Convert back to mixed number.
[tex]=4[/tex]
The unit cost for a yard is $4.
Hope this helps.
