Question 469433
Write a balanced equation:
{{{0.2x + 0.5(3000) = .25(x+3000)}}}
Solve for x
Distribute right side
{{{0.2x + 1500 = .25x + 750}}}
Subtract .25x on both sides
{{{-.05x + 1500 = 750}}}
Subtract 1500 on both sides
{{{-.05x = -750}}}
Divide by -.05 on both sides
{{{x = 15,000}}}
Therefore, 15,000 ml of 20% solution must be added
