Al sees this sign at a copy center. what is the least number of copies. al can make without losing any money

The sign states: 
1) Copies cost 10 cents each
2) Copy machines only take quarters
3) Copy machines do not make change. If you make 1 copy, you don't get 15 cents back. 

The least number of copies Al can make without losing money is 5.
