Question 827158
im no good at mixing problems but seen how its already answerted id give u my closest guess to guess n check version....
theres 14 total grams of this silver mixture and since 58% is closer to 60% then 50% there will be alot more of the 60% then of the 50% used
i started with 2 grams of 50% and 12 grams of 60% which comes out to 58.571428...repeating
so i upped it to 2.5grams and 11.5grams which comes to 
58.21428571428...
so i upped it to {{{highlight_green(2.8)}}}grams and {{{highlight_green(11.2)}}}grams which comes to
exactly 58%
