If you would like to know how much does the product cost per inch, you can calculate this using the following steps:
1 foot = 12 inches
75 feet = 75 * 12 inches = 900 inches
$48.50 ... 75 feet = 900 inches
$x = ? ... 1 inch
48.50 * 1 = 900 * x
48.50 = 900 * x
x = 48.50/900
x = $0.054
The correct result would be $0.054.
