Do Indonesians use dozens a lot? Is this a more traditional way of counting?
The answer should be: Sixty seven dozen. There is no 's' on the end of dozen. Explanation - Dozen is a collective noun used in two ways: (1) when preceded by a numeral always 'dozen' [two dozen eggs]; (2) in other plural uses, normally dozens [there were dozens of birds on the lawn; he made dozens of mistakes]. Reference: Fowler's Modern English Usage. So, in this instance, the answer is: sixty seven dozen
