Jordan asked if I could explain how I got to the price of £21.41 for one roll of wall paper, I wrote the workings on a previous post but hopefully this makes a little more sense as a step by step. I'm not really sure of any other way to explain it.  Hope this helps.

So 1 kg of pigment will cost £113.835

1 kg = 1 litre 

We already know from from the TechnoGlow website that 1 litre of glow pigment will cover 3.5 square metres. 

So to cover 3.5 square metres it will cost £113.835

A standard roll of wallpaper at 10 metres x 0.52 metres has the area of 5.2 metres squared.

We have estimated that are designs will require 10% of this area (5.2 m^2) to be printed in glow in the dark pigment.

10% = 0.52 metres squared

We then need to divide 0.52 squared (10%) by 3.5 squared (the area that 1kg will cover) = 0.14857 kg which is how much ink we are going to use to cover 10% of the surface area.

We then need to multiply this figure (0.14857 kg) by the cost of 1 kg of pigment which is £113.835 = £16.91

So the price to cover 10% of 1 roll of wallpaper with the pigment, will be £16.91

We then need to add on the £4.50 for the production costs to bring our final total to £21.41
