Question 661978: How many different ways can you receive change for $0.28 using quarters, nickels, dimes, and pennies?

You can put this solution on YOUR website!
If we use no quarter or dimes, then we can use from 0 through 5 nickels,
and the rest pennies. That's 6 ways.
If we use no quarter and 1 dime, then we can make the remaining 18 cents
using from 0 through 3 nickels, and the rest pennies. That's 4 ways.
If we use no quarter and 2 dimes, then we can make the remaining 8 cents
using 0 or 1 nickel, and the rest pennies. That's 2 ways.
If we use a quarter, then we can only make the remaining 3 cents
using 3 pennies. That's 1 way.
Total: 6+4+2+1 = 13 ways.
