.
A man has 4.55 dollars in change composed entirely of dimes and quarters. 
What are the maximum and minimum number of coins that he can have? 
Is it possible for the number of dimes to be equal the number of quarters?

<U>Answer</U>. Maximum number of coins that he can have is 1 quarter and 42 dimes, which is 43 coins in total.

        Minimum number of coins that he can have is 17 quarter and 3 dimes, which is 20 coins in total.

        It is possible for the number of dimes to be equal the number of quarters. 13 dimes and 13 quarters gives $4.55:  13*$0.1 + 13*$0.25 = $4.55.
