In my country i decided to develop my own currency.  Long tired of the decimal system, i decided to arbitrarily make a new currency system.  From now on 121 coins make 1 Bmad bill.  $121 one BMAD bills makes a hundred and so on.  Also, i decided that All numbers within each system must be reached by no more than five bills/coins.  In other words.  If i want 119 cents, then five coins or less must be enough to reach that amount.  If i want 120 cents, then i would use at most five coins too but it does not have to be the same five coins that made 119.  So to reach any price amount under a hundred, i would need at most five bills and five coins.

 

Three questions:

 

1. What is the fewest number of coins needed to make the above true?  What would be their values?

2. How many one BMAD bills are needed to make a million?

When the fiery moon rises and the frozen sun sets, then the war between good and evil shall come to an end. Until then I, the guardian of both heaven and hell, the keeper of destruction and bringer of peace, shall dream these lives to death and freedom.
