How many different ways are there to make 20 cents?

Answer 1

[1] 20 pennies is one way,

[2] Then take 1 nickel (5 cents) with 15 pennies

Then take 2 nickels with:

[3] 10 pennies

[4] or 1 dime

Then 3 nickels with:

[5] 5 pennies

[6] or another nickel (4 nickels total)

Take 1 dime with:

[7] another dime (2 dimes total)

[8] ten pennies

Eight ways should be it. Assuming the order of the coins is not important

( 1 dime and 2 nickels is the same as 2 nickels and 1 dime for example)
