The people living on Sesame Street all decide to buy new house numbers, so they line up at the store in order of their addresses: 1, 2, 3, . . . . If the store has 100 of each digit, what is the first address that won't be able to buy its house numbers?

for some reason i am getting 20 1's up to 100 (not counting 100).  I will recheck my numbers:

 

1-9 =1

10-19=11

20-99=8

I still get 20.
