Could someone tell me whats difference between a and per?
For example:1.The eggs costs 2$ a dozen.2.The eggs costs 2$ per dozen.
(please give me simple answers,Because. I am learning English.thank you.)
There is no difference in meaning between the two sentences.
There is an unspoken "for" in the first sentence. $2 for a dozen.
"Per" means "for each." So "$2 per dozen" = "$2 for each dozen."
