Too Much Noise (fewest number of coins for given amount)

Too Much Noise!

I like to scare my little brother. It is fun to make him yell and run!

He's such a baby!

Lately it has been really hard to sneak up on him because he can hear me coming. He hears the money in my pocket jingling.

I need my money for school lunches and supplies. How can I carry my money and still be quiet enough to scare my brother?

I think I should carry the same amount of money but fewer coins. Then he couldn't hear me.

Right now I have $0.48 in my pocket. I have one dime, four nickels, and eighteen pennies. That's 23 coins! What is the fewest number of coins I could carry and still have $0.48?

Yesterday my brother heard me coming when I had $0.81 in my pocket. I had three dimes, nine nickels, and six pennies. That's 18 coins. What is the fewest number of coins I could have had that still equals $0.81?

Last night my brother was playing with his truck when I sneaked up behind him. Just as I was going to yell "Boo!", he turned and looked at me. I bet he heard the 36 pennies in my pocket. What are the fewest number of coins I should have been carrying that equals $0.36?
