Max has a collection of dimes and quarters. He has 25 coins that total $3.70. What is the best method to use to find the number of quarters in the collection?
he can only have so many quarters before it goes over the maximum amount of $3.70. if theres 25 coins total of only dimes and quarters, you can find the maximum of them both, which will add up to be $3.70 exactly.
