Question

Brad goes to the store with exactly $1.00 in change. He has at least one of each coin less than half-dollar coin, but he does not have a half-dollar coin. What is the least number of coins he could have.

Answer 1

you need from the higher-valued coin the most
so start with the quarters,you can't have four because you'll have none of the other coins
so 3quarters=>0.75$
with the left 0.25$ do the same
