Question 820053
x=ml of 10% acid in solution
y=ml of 2% acid in solution

percentage(amount)+percentage(amount)=total percentage(total amount)
{{{.1x+.02y=2000(.08)}}}
{{{.1x+.02y=160}}}
Substitute {{{y=2000-x}}}
{{{.1x+.02(2000-x)=160}}}
{{{.1x+40-0.02x=160}}}
{{{0.08x=120}}}
{{{x=1500}}}
--------------
{{{y=2000-x}}}
{{{y=2000-1500}}}
{{{y=500}}}
--------------
1500 mL of 10% acid
500 mL of 2% acid 
creates 2000 mL of 8% acid
