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:
Given
Points = More than 80
Required [Missing from the question]
Represent as an inequality
Let p represents the number of points.
More than means greater than i.e. >
Hence, more than 80 is represented as;
Answer:362
Step-by-step explanation:
You need to multiply
28% equals 28/100. So, 28% equals 28 per 100.
