Question 856403: Mia has 33￠ in her pocket. She has only 3 pennies. What are all the different combinations of coins she could have?

You can put this solution on YOUR website! Maybe a tree diagram. If three pennies then she has 30 cents using dimes, quarters, or nickels, inclusive.
Not quite a tree diagram, but looking at some combinations which could give 30 cent value or other values...
Quarters______________Dimes____________Nickels___________Cents-Value
0_____________________0________________6_________________30
0_____________________1________________4_________________30
0_____________________2________________2_________________30
0_____________________3________________0_________________30
1___________________*You could work through these yourself.....
...
*Actually if using 1 quarter, the possible combinations becomes very quick to find. 1 quarter plus 1 nickel = 25 cents plus 5 cents = 30 cents.
