Question 893669: how many ways can you make $0.30 using dimes nickels and pennies?
I would like to know how to do it instead of just the answer plz.'' Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! Difficult to explain here, but you build a tree diagram. Start with the dimes, and work to progressively lower coin values.
0 dimes; how many ways can you choose nickels; for each of them how many ways can you choose pennies.
1 dime; how many ways to choose nickels; for each of them how many ways to choose pennies.
2 dimes; same set of questions.
3 dimes; This combination itself already makes $0.30.
