1.   Since the cost of the highly controversial PWR programme would have been spread over all the stations built, it has now become considerably more expensive per reactor unit.

2.   Bigger public schools can be cheaper per pupil, but nearly as expensive per graduate, since the big schools usually have more dropouts.

3.   Cereal more expensive per pound than meat?

4.   Sweet, tender, juicy and full of pork flavor, it is also quite a bit less expensive per pound than the more traditional loin roast.

5.   That does tend to be more expensive per square foot than many conventional houses, in part because of the high cost of wood.

6.   The moment it occurred to me that having a heart transplant is the only activity in the world more expensive per minute than skiing, I gave it up.
