Say I have 10 dog turds on my lawn. I want them all off.
One neighborhood teen says he’ll scoop up all my turds, at $10 bucks an hour. I calculate it will take him about 5 hours to do it, so roughly $5 a turd, though I can’t be certain about the exact per-turd cost.
Another teen says he’ll scoop turds for $4 a piece, but he only has three or four hours to spare, so my rough estimate is that he’ll get to 6-8 turds, though I can’t be certain about the exact number of turds that will be removed.
Which is the more efficient turd-removal strategy?
