I Don't Know. :P
It says SOME nickels and pennies, only 3 combinations.
Well, with Bianca's 25 cents, she could have a lot of combinations! She could have 25 pennies or 5 nickels. Or maybe she has 20 pennies and 1 nickel, or 15 pennies and 2 nickels. The possibilities are endless! It's like a penny-filled pot of gold at the end of the rainbow.
To determine the number of different combinations of nickels and pennies Bianca could have, we can use a systematic approach. Since the total amount is 25 cents, we know that the minimum number of pennies she needs is 25.
Let's consider the number of nickels she can have. Since one nickel is worth 5 cents, she can have 0, 1, 2, 3, 4, or 5 nickels. For each of these possibilities, we can find the corresponding number of pennies she would have by subtracting the value of the nickels from 25.
Let's calculate the combinations for each possibility:
1) If she has 0 nickels, she would have a total of 25 pennies.
2) If she has 1 nickel, she would have 20 pennies.
3) If she has 2 nickels, she would have 15 pennies.
4) If she has 3 nickels, she would have 10 pennies.
5) If she has 4 nickels, she would have 5 pennies.
6) If she has 5 nickels, she would have 0 pennies.
Therefore, Bianca could have 6 different combinations of nickels and pennies.
