Answer
The price of the tubing per inch would be 0.42 dollars.
Work Step by Step
Let x represent the price per 1 inch of tubing.
We set up the proportion and solve by finding the cross product.
$\frac{12.60}{x}$ = $\frac{30}{1}$
12.60 $\times$ 1 = 30 $\times$ x
12.60 = 30x
Divide both sides by 30.
0.42 = x
The price of the tubing per inch would be 0.42 dollars.
