x= 116
to get the answer plug in the numbers and to check the answer reverse do the problem
I remember doing this but I don’t remember my answers.
10 quarts of 20 % salt solution mixed with 5 quarts of 80 % salt solution to make 15 quarts of 40 % salt solution
<em><u>Solution:</u></em>
The final mixture is 15 quarts
Let amount of 20% solution to be mixed, be x
Then, the amount of 80 % solution to be mixed is 15 - x
Thus, we can say,
"x" quarts of 20 % salt solution mixed with (15 - x) quarts of 80 % salt solution to make 15 quarts of 40 % salt solution
thus, we frame a equation as,
Thus 10 quarts of 20 % solution is mixed
Then, 15 - x = 15 - 10 = 5
5 quarts of 80 % salt solution is mixed
