If the Franzia wine brand is three times as old as the Carlo Rosi, then the Carlo Rosi is 3*40 = <<3*40=120>>120 years old.
The total number of years the Carlo Rosi and the Franzia wine brands have been around is 120+40 = <<120+40=160>>160 years
The Carlo Rosi is four times older than the Twin Valley wine brand, meaning the Twin valley wine brand is 40/4 = <<40/4=10>>10 years old.
Together, the three bands have a total of 10+160 = <<10+160=170>>170 years of existence.
