To find the different combinations of nickels and pennies that Bianca could have with a total of 25c, we can use a systematic approach by considering all the possible numbers of nickels she could have.
First, let's assume that Bianca has no nickels (0 nickels). In this case, she would have 25 pennies.
Next, let's consider if Bianca has 1 nickel. A nickel is worth 5 cents, so if she has 1 nickel, the remaining amount would be 20 cents. This means she would have 20 pennies.
Continuing this pattern, we can determine the different combinations for each possible number of nickels:
- 0 nickels (25 pennies)
- 1 nickel + 20 pennies
- 2 nickels + 15 pennies
- 3 nickels + 10 pennies
- 4 nickels + 5 pennies
- 5 nickels + 0 pennies
Therefore, Bianca has a total of 6 different combinations of nickels and pennies that could add up to 25 cents.
