Question 113369:
1.If you add pure alcohol to a 15%alcohol solution, what percent alcohol are you adding, and how do you represent the percentage in decimal form?
2. If 4 gallons of alcohol is added to 2 gallons of a 15% percent solution, what percentage of alcohol is in the mixture? Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! .15X+Y WHERE X IS THE AMOUNT OF 15% ALCOHOL & Y= THE AMOUNT OF 100% ALCOHOL.
.15*2+4=Z*6 HERE THE Z IS THE PERCENT OF MIXED ALCOHOL CONTAINED IN THE 6 GALLONS.
.3+4=6Z
6Z=4.3
Z=4.3/6
Z=.717 OR 71.7% ALCOHOL.
