Please help with math! :-(

Hi all! I have a quick question. I'm not too good with math and I have a problem. I made 30 ml of 15 mg e-juice for my friend and now he tells me that he wanted 24 mg. I have 100 mg e-juice base and the question I have is how many ml of 100 mg e-juice do I add to the 30 ml to get it up to 24 mg. I know how to delude the base juice and used an online calculator for that but cant figure out the math in reverse basically. Thanks for any help!

put the recipe into a juice calculator, use 15 mg for the strength. Then plug in 24mg as the strength and subtract the amount of nic needed for the first from the amount needed for the second.

Thanks for the idea! I went and calculated what it would've taken to get to 24 mg then calculated to get to 15 ml (7.2 ml vs 4.5 ml) then subtracted the 7.2 from the 4.5 and got 2.7 ml thank you so much!

no prob

glad you did the math, I did it with 60mg because that's the last bottle of nic I got and it was already in the calc. Would have been pretty strong with 100mg/ml nic base and the number i suggested.
