How many dimes are there in a quarter

Dimes and quarters have ridged edges. Pennies and nickels have smooth edges. Keeping these facts in mind, grab a whole bunch of coins and take a shot at these fun games! A dollar is worth cents. Using only pennies, nickels, dimes, and quarters, there are many different ways to make a dollar.

Let's have some fun with different combinations. Using more than one type of coin, what is the smallest number of coins you can use to make a dollar?

Using more than one type of coin, what is the largest number of coins you can use to make a dollar? Have one person think of an amount of money and another person make that amount using only pennies, nickels, dimes, and quarters. If playing with a group, see who can make the amount first! How can we represent this using our variables? But what do we do now? Well, if you had 10 quarters, how much money would you have? How can you figure it out? So what if I have "q" quarters? Well then I have. So how can I represent the total amount of money by having "d" dimes and "q" quarters?

Personally, I like elimination, but if you prefer substitution send me an email and I'll work it out that way. How many quarters and dimes does he have? Write a system of equations to solve. Fred has 3 times as many dimes as quarters. Julie is going to the mall. She has the same number of pennies as she does dimes. If she has 3 pennies, how many quarters, dimes. She has 4 more quarters than nickels.

How many of each type of coins does she have? Ben has a collection of 15 coins in quarters and dimes. There are 7 quarters in the collection. Is the ratio of quarters to dimes the same as dimes to quarters?

If there are 23 coins in all, how many of each does she have?
