A chemist needs 150 milliliters of a 65% solution but has only 32% and 77% solutions available. Find how many milliliters of the 77% solution you need to get the desired solution.
\n" ); document.write( "-----------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "active + active = active
\n" ); document.write( "0.32x + 0.77(150-x) = 0.65*150
\n" ); document.write( "Multiply thru by 100
\n" ); document.write( "32x + 77*150 - 77x = 65*150
\n" ); document.write( "-45x = -12*150
\n" ); document.write( "x = 40 ml (amt. of 32% solution needed in the mixture)
\n" ); document.write( "--------------
\n" ); document.write( "150-x = 110 ml (amt. of 77% solution needed in the mixture)
\n" ); document.write( "========================
