A certain 18-hole golf course has par-3, par-4, and par-5 holes, and there are twice as many par-4 as par-5 holes. How many holes of each type are there if a golfer has a par on every hole for a score of 70?
\n" ); document.write( "---------------
\n" ); document.write( "Let number of par-5 holes be \"x\"; par-strokes for these is 5x
\n" ); document.write( "Number of par-4 holes is \"2x\"; par-strokes for these is 4(2x)=8x
\n" ); document.write( "Number of par-3 holes is \"18-x-2x\"=\"18-3x\"; par-strokes for these is 3(18-3x)
\n" ); document.write( "=54-9x
\n" ); document.write( "--------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "5x+8x+54-9x=70
\n" ); document.write( "4x=16
\n" ); document.write( "x=4
\n" ); document.write( "# of par-5 holes is x=4
\n" ); document.write( "# of par-4 holes is 2x=8
\n" ); document.write( "# of par-3 holes is 18-3x=6
\n" ); document.write( "================
