## Elementary Algebra

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.
