A chemist mixed a 15% glucose solution with a 35% glucose solution.This mixture produced 35 liters of a 19% glucose solution. How many liters of each solution did the chemist use in this mixture?\r
\n" ); document.write( "\n" ); document.write( "Let x be the quantity of 15% solution mixed
\n" ); document.write( "Let y be the quantity of 35% solution mixed\r
\n" ); document.write( "\n" ); document.write( "(15/100)x+(35/100)y = (19/100)35
\n" ); document.write( "0.15x+0.35y=0.19*35=6.65 ----1\r
\n" ); document.write( "\n" ); document.write( "x+y=35
\n" ); document.write( "Multiply this equation by 0.15
\n" ); document.write( "0.15x+0.15y=5.25 -----2
\n" ); document.write( "substract 2 from 1\r
\n" ); document.write( "\n" ); document.write( "0.2y=1.40
\n" ); document.write( "y= 7 liters
\n" ); document.write( "x=35-7=28\r
\n" ); document.write( "\n" ); document.write( "the quantity of 15% solution mixed = 28 liters
\n" ); document.write( "the be the quantity of 35% solution mixed = 7 liters\r
