x how many trips Bob makes
\n" ); document.write( "y how many trips Doug makes\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Account for trips: x+y=300.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Account for water volume: 5x+3y=1140.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Two equations in two unknowns, solve any way you want. Suggestion is multiply the trip account equation by 3, and use elimination to start with.
