What is the connotative meaning of “a dime a dozen?”

1. Something is very rare.
2. Something is very expensive.
3. Something is very common.

Respuesta :

Answer: It's 3

Explanation: a dime a dozen just look at it we can see a dime=10 and a dozen=12 so Answers 1 and 2 would not make that much sense because 10/12 will mean it is a common thing not a rare or expensive thing
