If I add one ounce of 75.5% alcohol to a 25 ounce of 10% wine
what would be the final %?
-------
Equation:
alch + alch = alch
0.10*25 + 0.755*1 = x(25+1)
--------------------------------
Multiply thru be 1000 to get::
100*25 + 755*1 = 26000x
--
2500 + 755 = 26000x
---
x = 3255/26000
---
x = 0.1252 = 12.52%
----------------------------
