Jason has 20 coins that are only dimes and quarters. The total value is $2.75. How many of these are quarters?

I tried answering it but I got 5 quarters. I'm not so sure if that's the right answer. Can you show me the equation and the right answer to see if I'm correct? Thanks!

Let's start with your answer. Five quarters = $1.25. 2.75 - 1.25 = $1.50.

Fifteen dimes = $1.50.

Your answer is right.
