How many yodelers and xylophones are on the gondola? I wrote it as:
\n" );

document.write( "so x+2y=$40 but how do I use the subtraction/addition method if I have no equation to add or subtract to? Here is where I am stumped. \n" );

Algebra.Com's Answer #624016 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! A gondola conductor charges $2 per yodeler and $1 per xylophone. It cost $40 for the entire club including xylophones to ride the gondola. 2 yodelers can share a xylophone, so the number of yodelers on the gondola is twice the number of xylophoners.
