A brown flask contains a concoction that is 20% alcohol. A red flask contains a concoction with an unknown amount of alcohol. An equal amount of both flasks is poured into an empty jug. If the resulting mixture has an alcohol concentration that is 30% greater than the alcohol concentration of the brown flask, what percent alcohol did the red flask originally contain?

Best ResponseYou've already chosen the best response.0first off the alcohol concentration in the brown flask is 20% now we have to be careful about what the final alcohol concentration is, it is NOT 50%

Best ResponseYou've already chosen the best response.0unless they wrote the question carelessly did you notice that they did not say how much of anything there was?

Best ResponseYou've already chosen the best response.0yes, 20% more than the original 20% is \(20\times 1.3=26\) for sure

Best ResponseYou've already chosen the best response.0now lets imagine there are 100 liters in each flask to make the numbers easy

Best ResponseYou've already chosen the best response.0I think it's 26% because the concertation is 30% greater than the brown=23% of alcohol. Then 23% is the average of the brown and the red, so it is 26% for the red flask.

Best ResponseYou've already chosen the best response.0because when you are done, the total percent alcohol is 26%

Best ResponseYou've already chosen the best response.0so the red flask must have a higher concentration of alcohol than that i find it easiest to work with numbers

Best ResponseYou've already chosen the best response.0say each has 100 liters, the brown flask has 20 liters, of alcohol, the brown one unknown liters of alcohol (that is what we are trying to find)

Best ResponseYou've already chosen the best response.0when you mix them together, you have 200 liters total, and it is 26% alcohol 26% of 200 is 52 so there are 52 liters of alcohol total

Best ResponseYou've already chosen the best response.020 liters came from the brown flask, the other 32 liters came from the red flask

Best ResponseYou've already chosen the best response.0yeah i can see why it is confusing first because they are using "percent' to mean two different things

Best ResponseYou've already chosen the best response.0so I know they had 26% but how do you find what's in the red flask?

Best ResponseYou've already chosen the best response.0you notice that they do not say how much each flask holds right?

Best ResponseYou've already chosen the best response.0so it doesn't matter if it doesn't matter, then you can pick a number, work with that number, and whatever answer you get will be right

Best ResponseYou've already chosen the best response.0if you are working with percents, the easiest number to pick is 100

Best ResponseYou've already chosen the best response.0so we say each has 100 liters ok?

Best ResponseYou've already chosen the best response.0the brown one has 20% alcohol that means it contains 20 liters of alcohol

Best ResponseYou've already chosen the best response.0mix them together, 100 liters + 100 liters is 200 liters

anonymous

Best ResponseYou've already chosen the best response.0it is 26% alcohol and 26% of 200 is 52, so there are 52 liters of alcohol in the total 200 liters

Best ResponseYou've already chosen the best response.020 of them came from the brown flask, so the remaining \(5220=32\) liters came from the red flask

Best ResponseYou've already chosen the best response.0that means the red flask had 32 liters of its 100 liters as alcholol

anonymous
