How many different ways can you make 23 cents in change?

Assuming you're American:

1. 23¢ = 23 × 1¢
2. = 18 × 1¢ + 5¢
3. = 13 × 1¢ + 2 × 5¢
4. = 13 × 1¢ + 1 × 10¢
5. = 8 × 1¢ + 3 × 5¢
6. = 8 × 1¢ + 1 × 5¢ + 1 × 10¢
7. = 3 × 1¢ + 4 × 5¢
8. = 3 × 1¢ + 2 × 5¢ + 1 × 10¢
9. = 3 × 1¢ + 2 × 10¢

So there are 9 different ways.

If you were European, there would also be a 2 cent coin and a 20 cent coin to consider in the mix.
