Suppose that you have a supply of a 25% solution of alcohol and a 15% Solution of alcohol. How many parts 1/5 times 3/2x times

Your first question is incomplete:

I think the missing part is as follows

Q.Suppose that you have a supply of a 25% solution of alcohol and a 75% solution of alcohol. How many quarts of each should be mixed to produce 70 quarts that is 35% alcohol?

Ans:

alcohol + alcohol = alcohol

Let x=amount of 25% solution needed in the mix.

0.25x + 0.75(70-x) = 0.35*70
Multiplying both sides by 100 we get,

25x + 75*70 - 75x = 35*70
-50x = -40*70
x = 56 quarts (amount of 25% solution needed in the mix)
70-x = 14 quarts (amount of 75% solution needed in the mix)
