Mrs. G thinks a slightly altered version of the same medicine might very well clear up her gooey scalp. Now she is mixing a liquid containing 12% reactor fuel with a liquid containing 32% reactor fuel to create a 4 ounce liquid containing 20% reactor fuel. How many ounces of the 12% liquid must she use? Round to the nearest one decimal place(tenths).
\n" ); document.write( "

Let amount of 12% liquid to mix, be T
\n" );
document.write( "Then amount of the 32% liquid is, 4 - T
\n" );
document.write( "We then get: .12T + .32(4 - T) = .2(4)
\n" );
document.write( ".12T + 1.28 - .32T = .8
\n" );
document.write( ".12T - .32T = .8 - 1.28
\n" );
document.write( "- .2T = - .48
\n" );
document.write( "Amount of 12% liquid to mix, or  \n" );
