A problem to get
is the fewest number of coins that it will take to make 43 cents if you have
available pennies, nickels, dimes, and quarters? After
you have solved this problem, provide an
explanation that proves that your answer is correct?
does the answer (and the justification) change if you only have pennies,
dimes, and quarters available?
We first encountered this problem in a conversation with Deborah Ball.
