You can put this solution on YOUR website!
0.03x+0.06(30-x) = 0.05(30)
\n" ); document.write( "0.03x+1.8-0.06x = 1.5
\n" ); document.write( "-0.03x = -0.3 Divide, and remember that -/- = +
\n" ); document.write( "x = 10
\n" ); document.write( "You'll need 10 gallon of the 3% solution and 90-10 = 80 gallon of the 6% solution to obtain 90 gallon of a 5% solution
