All you have to do is basically divide and make a diagram
The volume of 10% solution will be 6 l and 9 litre of the 30 % solution will be taken.
<h3>What is Volume ?</h3>
Volume is the space occupied by a three dimensional object .
The concentration of solution required is 22% acid
The concentration of solution available is 10% and 30%
The total volume required is 15 liters
The formula for making a mixture is
Concentration = ( m₁x₁ +m₂x₂) / (x₁+x₂)
22 = (10 * x + 30 *(15 -x))/( 15)
10 x + 450 - 30x =330
-20x = -120
x = 6
The volume of 10% solution will be 6 l
and 9 litre of the 30 % solution will be taken.

Step-by-step explanation:
x=√7+√5, y=√7-√5
therefore, xy = (√7+√5)(√7-√5) = 7-5 = 2.
Hope this helps you.
You are given the function 
Express t:
This expression gives the month t in terms of the price p.
If I'm right, then the answer would be B. 800. Hope I helped!
