Всем привет!

Буду очень благодарна, если вы поможете перевести фразу "bob total of operators" в следующем предложении:

One of the earliest definitions of tourism was provided by the Austrian economist in 1910, who defined it as, "bob total of operators, mainly of an economic nature, which directly relate to the entry, stay and movement of foreigners inside and outside a certain country, city or a region."

bob total = sum total = совокупность
