You can put this solution on YOUR website!
Not well stated. Maybe you mean something like this:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Two grades of milk are 2.5% butterfat and 5% butterfat. How many gallons of each should be mixed to give 100 gallons of milk which is 4% butterfat?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The equations which would let you find the quantities of each grade of milk to use would be, if u is how much 2.5% fat and v is how much 5% fat milks,\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%282.5u%2B5.0v%29%2F100=4\"$ and $\"u%2Bv=100\"$
\n" ); document.write( "Solve the system for u and v.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The lesson which will explain this more thoroughly is \"Mixing two concentrations for known amount of mixture\", which you find in the lessons link in my profile. \n" ); document.write( "

\n" );
