This is for constructions using [p en/per] or [p en/by] to specify a unit:

- [ex 001 "The cost is $10 [p en/per RateUnit] item."]

- [ex 002 "A fuel efficiency of 40 miles [p en/per RateUnit] gallon (of gas)"]

- [ex 003 "Pizza is sold [p en/by RateUnit] the slice."]

- [ex 004 "They charge [p en/by RateUnit] the hour."]

Paraphrase: The adposition can be paraphrased as “for each/every”.
