Yes, it specifies the population
Let there be x quarts of the 20% salt solution, and (25 - x) quarts of the 80% salt solution.
Then the total amount of salt in the 20% portion would be 0.2x, while that from the 80% portion would be (0.8)(25 - x). This would have to total up to (0.44)(25) in the final solution, so the equation is:
0.2x + 0.8(25 - x) = (0.44)(25)
-0.6x + 20 = 11
x = 15 quarts of the 20% salt solution
25 - x = 10 quarts of the 80% salt solution
This is a common math problem. There are two ways to answer this question but both will give you the same answer. There is a misconception that this can also equal 40. If someone posts that the answer is 40, please let me know and I will explain why that is not actually the answer.
1+4=5 2+5=7
3+6=21
8+11=
These equations are actually:
1*(4+1)=52*(5+1)=7
3*(6+1)=21
8*(11+1)=96
Therefore:
8+11 = 96
52 divided by 8 = 6.5 hope this helps you!
