In a recent survey of musical preferences among BrainDen'ers, it was determined that
280 like jazz; 254 like classical; 280 like country/western.
97 like both jazz and classical; 138 like both classical and country/western; 152 like both country/western and jazz.
Only 73 like jazz and classical and country/western.

How many BrainDen'ers were interviewed?
