Help with my math please!

A few people helped me before so thanks! They changed the rules in New Zealand again and I could only get this bottle of 30 ml. It looks like 50 mg of nicotine in the 30 ml bottle.
I use 18 mg. nicotine for my vape and I have no idea how to mix it. I generally throw in some VG with my PG, but at this point it seems so complicated I could use just PG to mix.
Can anyone help? I would be eternally grateful!

18/50 = .36 = 36% = a little more than 1/3.
Keep it simple: Triple the volume of e-liquid, or a little less than triple, to get about what you want: 50/3 = 16 1/3 mg/ml

Or more precisely: Add 53 1/3 ml to your 30 ml to get 18mg/ml or 1.8 % = Add 5 1/3 ml to each 3 ml.
