How Many To Return?


You have stealthily raided your small child's piggy bank.  Later, you 
start to feel guilty and decide to return the money.  When you counted
the money originally, you had the same number of dimes as quarters, 
and took exactly $2.45.  When you put it back, how many of each coin 
will you need to replace, knowing that your child keeps a record of how
much he puts in and in what denomination, of course?
