How much should I price this rug?

I’m not very good at fairly pricing my rugs, I just don’t really know how exactly to go about it. I also want to make sure I’m making a decent profit.

The rug took pretty much 2 full acrylic wool yarns of white and 2 full yarns of black £11, anti slip backing cost me £24 for 2x2m, used no more than 2 glue sticks the pack of 12 coats about £2, spray adhesive can cost about £3, primary fibre lock adhesive cost about £24 for 12kg.
