Answer
The price of the trim per yard would be 12.9 dollars.
Work Step by Step
We need to multiply the price by the ratio that converts inches to yards.
The ratio that converts inches to yards is $\frac{12\ inches}{1\ foot}$ $\times$ $\frac{3\ feet}{1\ yard}$ = $\frac{36\ inches}{1\ yard}$
So, $\frac{8.60\ dollars}{24\ inches}$ $\times$ $\frac{36\ inches}{1\ yard}$ =
$\frac{8.60\ dollars\ \times\ 36}{24\ yard}$ =
$\frac{309.6\ dollars}{24\ yards}$ =
$\frac{12.9\ dollars}{yard}$ = 12.9 dollars per yard
The price of the trim per yard would be 12.9 dollars.
