Difficult Danny has acquired his nickname (and some other, less polite nicknames) due to the fact that, whenever he buys anything, he insists upon paying the exact amount, with precisely 100 pieces of currency. Danny walks into McArnold's and orders an iced coffee for $1.99. He pours 100 coins onto the counter, using some number (possibly zero) of each of the following: pennies, nickels, dimes, quarters. There are equal, non-zero quantities of dimes and quarters. What is the breakdown of coins that Difficult Danny used to pay for his iced coffee?

(See hint for currency values.)

How would he pay for anything that's 10,000,000.01+ US dollars?

Well, I can't say I know all about Danny's life, but I'm guessing that he is not lucky enough to ever encounter that problem.

Perhaps he would use a check as one of the "pieces of currency."

The opening line alone makes this teaser totally worth it!

And brilliant response to the comment above, by the way!

Eighsse could you pm me and tell me the method of how you figure this sort of problem out?

(sorry for my stupid brain :laugh
