how is the volume of a solution used in calculating concentration?
Let
A------------> <span>number of children
B------------> </span><span>number of adults
we know that
0.40A+0.70B=5.90--------------------------> equation 1
A+B=11------------> A=11-B----------------> equation 2
using a graph tool------------> to resolve the equations system
see the attached figure
the solution is
A=6
B=5
the answer is
A is bigger</span>
0-4 stay the same 5-9 plus one
Which is 1,500
