Answer:
you did not provide the numbers to answer any question...
but the formula that you want is probably this one
Combination Formula nCr=n!(n−r)!r!
Step-by-step explanation:
<em>x</em> = liters of 1% solution
<em>y</em> = liters of 5% solution
<em />
<em>x</em> + <em>y</em> = 16
0.01<em>x</em> + 0.05<em>y</em> = 0.04*16 = 0.64
<em />
<em>y</em> = 16 - <em>x</em>
<em />
0.01<em>x</em> + 0.05(16 - <em>x</em>) = 0.64
0.01<em>x</em> + 0.8 - 0.05<em>x</em> = 0.64
0.16 = 0.04<em>x</em>
<em>x</em> = 4
<em>y</em> = 12
