There are 13 different combinations. For any combination, the number of pennies P, nickels N, Dimes D, and Quarters, P + 5N +10D + 25Q = 25 (1, 5, 6, 1) where P = 0, 5, 10, 15, 20, 25 N = 0 to 5 D = 0 to 2 Q = 0 or 1 The combinations are 1 quarter 2 dimes and 1 nickel 2 dimes and 5 pennies 1 dime and 3 nickels 1 dime, 2 nickels, 5 pennies 1 dime, 1 nickel, 10 pennies 1 dime, 15 pennies 5 nickels 4 nickels, 5 pennies 3 nickels, 10 pennies 2 nickels, 15 pennies 1 nickel, 20 pennies 25 pennies
Three quarters and a dime or two nickels. There are other combinations as well, such as 85 pennies.
I am assuming this means what different combinations of coins would add up to 17 cents. You could have one dime, one nickel and 2 pennies, 1 dime, 7 pennies 3 nickels, 2 pennies 2 nickels, 7 pennies 1 nickel, 12 pennies 17 pennies
10 quarters 7 dimes 9 pennies and 27 nickels is: $4.64

There are 13 different combinations. For any combination, the number of pennies P, nickels N, Dimes D, and Quarters, P + 5N +10D + 25Q = 25 (1, 5, 6, 1) where P = 0, 5, 10, 15, 20, 25 N = 0 to 5 D = 0 to 2 Q = 0 or 1 The combinations are 1 quarter 2 dimes and 1 nickel 2 dimes and 5 pennies 1 dime and 3 nickels 1 dime, 2 nickels, 5 pennies 1 dime, 1 nickel, 10 pennies 1 dime, 15 pennies 5 nickels 4 nickels, 5 pennies 3 nickels, 10 pennies 2 nickels, 15 pennies 1 nickel, 20 pennies 25 pennies
In each combination, you can have 0,1,2 or 3 pennies; you can also have 0 or 1 nickels, 0 or 1 dimes and 0 or 1 quarters. That is, 4 ways of picking the number of pennies, 2 ways of picking how many nickels, 2 for dimes and 2 for quarters. In all that makes 4*2*2*2 = 32 combinations. BUT, one of these combinations is where you have 0 pennies, 0 nickels, 0 diems and 0 quarters. Conventionally, a null combination such as this is omitted and so you have 31 valid combinations.
