What two coins make 30 cents?
If you’ve ever been faced with this puzzling question, you may have had a moment of confusion. Fear not, for the solution is not as elusive as it may seem. The two coins that add up to 30 cents are a quarter and a nickel.
When it comes to coins, it’s easy to assume that the combination should include pennies due to their low value. However, in this particular scenario, pennies are not part of the equation. Instead, we must look to the quarter and the nickel to find the answer.
A quarter is worth 25 cents, and a nickel is worth 5 cents. When you add these two coins together, their total value amounts to 30 cents. It’s as simple as that!
