The gondola conductor charges $2 for
each yodeler and $1 for each xylophone.
It costs $40 for the entire club, including
the xylophones, to ride the gondola.
Two yodelers can share a xylophone, so
the number of yodelers on the gondola is
twice the number of xylophones.
How many yodelers and how many
xylophones are on the gondola? Represent this problem with a system of equations. Let x represent the number of xylophones and let y be the number of yodelers.
