Question

please help me solve if 1 gallon of water is added to 6 quarts of a mixture of alcohol and water that is 50% alcohol, what percent alcohol is the resulting mixture?

Answer 1

I got 30

Explanation:

6 quarts that means 3 is water 3 is alcohol

When you add in a gallon you get 4 more quarts of water right?

That would be 7 quarts of water and 3 quarts of alcohol

7+3=10 3/10 to x/100 x= 30%hope this is correct and hope it helps :)
