Four different coins are used in Australia with values of 5, 10, 20, and 50 cents. The Australian coins in Farmer Tim's pocket have a total value of \$3.95, and he has at least one of each coin. What is the smallest number of coins that he could have in his pocket?

This Question is from my teachers' test, and he told us find the answers. I need a HINT not the answer pls

You can't have 8 50-cent pieces, but you can have? And the difference is made up from the 3 remaining coins.

Imagine you are a cashier and need to give a customer back some change, and you want to return the fewest number of coins to the customer as possible. For example, if the change due was 50 cents, you would never return ten 5 cent coins when you could just return one 50 cent coin.

To ensure that you return the fewest coins possible, you might think through these steps in order:

1. Return the maximum number of 50 cent coins that you possibly can.

2. Return the maximum number of 20 cent coins that you possibly can.

3. Return the maximum number of 10 cent coins that you possibly can.

4. Return the maximum number of  5 cent coins that you possibly can.
