Ok, I am trying to figure something out but for some reason my brain is not registering. It is either:
1. Too damn cold here in upstate NY and my brain froze.
2. It's too early in the morning.
3. I am a moron
Anyways, Here is what i am trying to figure out. I have a bunch of scrap gold that i am taking to the refiners today and am trying to figure out the average karat percentage of the lot so i have it to compare with what the refiner assays it as.For some reason i can't figure out how to do it.
I have:
131.5 grams 10k (41.7% pure gold)
247 grams 14k (58.5% pure gold)
58.5 grams 18k ( 75% pure gold)
21 grams 21k (87.5% pure gold)
So basically what i am looking for is the average percentage to fill in this sentence.
I have 458 grams of gold @ a pure gold percentage of _______.
Thanks in advance to all those who can help.
Btw, If you chose answer 3 you probably win the prize.
