Calculate Material Cost for Vinyl Edging

What happens here

For vinyl edging (referred to as 'Blackjack' edging), it is recommended to use straight-line sticks instead of rolled material, as they are easier and faster to install, despite a slightly higher initial cost. As an example, a 20 lineal-foot straight-line stick of good quality vinyl edging costs about $16 plus tax. For calculation purposes, this is rounded to $20 for 20 lineal feet, resulting in a material cost of $1.00 per lineal foot.

Goal: Determine the per-lineal-foot material cost for vinyl edging
