Answer:
Equation:
HCL + HCL = HCL
0.30x + 0.45(50-x) = 0.35*50
Multiply thru by 100 to get:
30x + 45*50 - 45x = 35*50
-15x = -10*50
x = (2/3)50
x = 33 1/3 liters (amt. of 30% solution needed in the mixture)
50-x = 16 2/3 liters (amt. of 45% solution needed in the mixture)

Step-by-step explanation:
Answer:
about 36 and 24 liters
Step-by-step explanation:
a+b = 60 1
let A multiplied by 10 percent and B multiplied by 35 percent then
10 a + 35 b = 1500 ( 60 * 25 ) 2
add no. 1 to 2 and multiply no.1 by -10
-10 a+ -10 b = -600
10 a+ 35 b = 1500 adding
then 25 b = 900 then b = 36 liter
then a = 24 liter
