A moonshiner fills her still with 4,600 pounds of an alcohol and water mixture called "sour mash". The alcohol content of the "sour mash" is 12%. The alcohol content of the "white lightning" still overheads product that she will sell is 50% (100 proof). The waste from the still bottoms that she will throw away weights 3,650 pounds. What is the concentration of the alcohol in the waste from the still bottoms? Check your answer by calculating the active concentration with the 50% active amount.
