You can put this solution on YOUR website!
“Attack” is 2% acid and “Blast” is 6% acid. They want to mix the two to get 60qt of a solution that is 5% acid. How many quarts of each should they use?
\n" ); document.write( ":
\n" ); document.write( "Let x = the amt 6% acid stuff
\n" ); document.write( "then
\n" ); document.write( "(60-x) = the amt of 2% acid stuff
\n" ); document.write( ":
\n" ); document.write( "Write the decimal equiv equation:
\n" ); document.write( ".06x + .02(60-x) = .05(60)
\n" ); document.write( ":
\n" ); document.write( ".06 x + 1.2 - .02x = 3
\n" ); document.write( ":
\n" ); document.write( ".06x - .02x = 3 - 1.2
\n" ); document.write( ":
\n" ); document.write( ".04x = 1.8
\n" ); document.write( "x = \"1.8%2F.04\"
\n" ); document.write( "x = 45 qts of 6% acid
\n" ); document.write( "then
\n" ); document.write( "60 - 45 = 15 qts of 2% acid
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in original equation:

\n" ); document.write( " 2.7 + .3 = 3 \n" ); document.write( "
