There is a stack with 2018 numbered cards (from 1 to 2018). Corinne decided to remove all cards that ended in 0, and then number them again starting from 1. If she removes once more the cards that have a number that ends in 0, how many cards are left?

How many numbers between 10 and 100 end in zero??! If you can answer that correctly, you should be able to answer your question.
