What Are Friends For?

Eddie and Charley are friends. Eddie writes rather slowly and his lucky number is 8. They are sitting at the table and chitchatting at Charley's apartment. Eddie asks Charley to lend him $200. Charley hands him an A4 paper and a pencil and says: 'I will lend you the money if you write the digit 8 two hundred times within one minute.' Charley then takes a stopwatch and says: 'Your time begins............... now!'. Charley activates the stopwatch and Eddie starts to write as fast as he can. The time elapses and Eddie fails as he wrote the digit 8 a hundred times only. But a few minutes later Eddie has an idea because of which Charley lends him the money. What happened?

He convinced Eddy that if 200 8s are worth $200, then surely 100 8s must be worth $100.

He turns the page 180o and discovers a hundred more 8's right there in plain sight.

Your answer is witty. I needn't tell you that it is incorrect.

Nice try! Your neat idea is the answer to a similar and a better riddle where Eddie has to write 200 digits of his choice and then he writes a hundred 9's or 6's. Or he has to write his lucky number 9 so that there are 200 digits.
The intended answer is unoriginal and perhaps a bit lame.

If that's what we're looking for:
- Eddie explained that "if" is not the same thing as "if and only if".
- Eddie suddenly had a brilliant business idea that Charley would happily invest $200 in.
- Eddie pulled out a gun.

Developing on SMQ's idea - instead of rotating the paper in the same plane flip it about to the other side?
And claim the imprints of the existing 100 8's from the original side showing through on this side as the extra 100 8's making it a total of 200 8's.

1). Eddie put a mirror next to the written 100 8s?
2). Eddie took a picture of the written 100 8s? (with his cell phone)

Nice try.
The answer to this riddle and a well-known riddle is cast in the same mold.

Charlie is weak in Maths. So Eddie proved that 100 = 200 by using the flawed proof of 1 = 2

Instead of flipping the paper 180 degrees, he could just flip it 90 degrees. A finite amount of infinities must be more than 200, rite?

When I was contemplating the puzzle, I didn't bear infinity in mind. In mathematics, "infinity" is often treated as if it were a number.
On a side note, is it possible that infinities cancel each other out?
EINSTEIN: G sub I, J of t as t approaches infinity.
BARCLAY: G of t over G naught.
EINSTEIN: So it is, so it is.
BARCLAY: I still don't see how you're going to incorporate quantum principle into general relativity without adjusting the cosmological constant a lot more than you're doing here.
EINSTEIN: If we increase the value as you suggest, we must face the possibility of twenty six dimensions, instead of ten.
BARCLAY: I don't think I could deal with that.
EINSTEIN: I certainly could not.
BARCLAY: If the semiset curved into the subatomic, the infinities might cancel each other out.
EINSTEIN: Gruss Gott. They just might.
