A comrade came up with this answer for the question pictured above.
"16 because caramel makes sheep's bladder toasters wear smoke."
Ah yes I came up with the same solution.
However there was that unspecified "wind resistance". Which given the car's rate of speed I calculated to be...no not the same 20KM/H, but 16.5KM/H. This throws the whole equation off.
So in taking the 16.5KPH wind resistance into account Pedro ceases to exist in this continuum.
We can if you like speculate as to where he went, but for the sake of brevity I'll hold off for now.
The key to this equation is the "Triangle".
These musical instruments are usually made of steel. Sometimes an exotic alloy, but for again the sake of brevity we'll say standard instrument steel. The human arc of throwing due to gravity is 9.8 m/s2 directed downward.
That plus the now known wind resistance. The triangle landed off the road 8 meters from the original moving point of projection.
This being so Ralph Bennett a homeless vet living by the side of this road finds the triangle. He eventually sells it, and has just enough for pastries for himself, and his fellow vets back at the camp.
Ralph buys 20 assorted day old pastries. Doughnuts Cream Puffs Napoleons Croissants, and six coffee's that the cook threw in free,...hey it's for our vets.
The answer is of course "20 assorted pastries." ...plus one Soul. Pedro's.
This is not counting the pastries that Pedro bought on the parallel earth he appeared in.
That is another calculation entirely.
Still lets give it a thought.
When Pedro attempted to buy 'his' pastries one of his bank notes was a trifle off. It seems on this other earth the U.S. one dollar bill has the portrait of "Arron Burr" on it. Still his Five was good so he wasn't shot, and tagged by the clerk which is the law over there.
A friend asked me how I came by the skill to answer this arcane question so quickly, and clearly.
Well you must remember it was the mid-late 1960's when I was studying math. Quite by accident I got high in the boys crapper then went to class. I was amazed to realize how much LSD Speed, and what we called Wacky Weed quickened the mind. After that math was no problem.
Some of us even in time with assorted custom enhancements came up with equations for slip streaming hyper quantum waves as to make faster than light communications, and with some tweaking hyper-space faster than light travel possible.
Though not for organic matter.
An astronaut traveling through...well for want of a better term...Dark-Matter Space. Such a pilot, and crew would have a profoundly bad day or I should say eternity.
You see the Dark Universe is actually hell...I mean the real deal hell. Evil trapped spirits, and such. I can tell you we had some interesting adventures stuffing that crowd back into their box. However with un-personed probes it would be no problem.
These interstellar probes we long ago calculated could be sent to the nearby systems in a few moments. We of course kept this ourselves even to this day. I mean imagine what the current crop of world leaders would do with this. Mr. trump being exhibit "A".
...anyway I hope this answers any questions.
Comments from one of my Facebook readers:
Charles Taintor: You can't fool me, Pedro can't buy human souls but he can sell his own for a cupcake or anything else he can negotiate. The deal is non-cancellable.
Sidney Smith: Pedro of course was not selling 'his' soul. The original question was how many cupcakes for 'a' soul. ....Not Pedro's.
Selling one's soul for a pastry no matter how good is a sucker bet in the extreme. Knowing Pedro he'd never do this. However being a bastard Pedro 'would' sell someone else's soul.
One can in fact sell the souls of others. Dante alludes to this several times. Though not where you think. Just whose soul, and how Pedro came by it was never specified in the equation.
Charles Taintor: The Devil isn't "in the details", the Devil 'IS' the Details.
Sidney Smith: Of course. Lucifer himself told me this. As to how we came to meet is another matter for another time.
