John earned $240 in the summer by working at a fast food restraunt and baby-sitting. If he earned five times as much in the restraunt as he did baby-sitting, how much did he earn at each job?
\n" ); document.write( ".
\n" ); document.write( "if you have two unknowns, you'll need two equations.
\n" ); document.write( ".
\n" ); document.write( "Instead:
\n" ); document.write( "Let x = amount earned baby-sitting
\n" ); document.write( "then from \"he earned five times as much in the restraunt as he did baby-sitting\" we have
\n" ); document.write( "5x = amount earned in restaurant
\n" ); document.write( ".
\n" ); document.write( "x + 5x = 240
\n" ); document.write( "6x = 240
\n" ); document.write( "x = $40 (baby-sitting)
\n" ); document.write( ".
\n" ); document.write( "restaurant:
\n" ); document.write( "5x = 5(40) = $200
\n" ); document.write( " \n" ); document.write( "
\n" );
