To solve this problem, we need to find two coins with a combined value of 30 cents without using a nickel. Given that one of the coins is not a nickel, the other coin must be a nickel.
To identify a possible solution, we can look at the different coins and their values. Here are some common US coins and their values:
- Penny: 1 cent
- Nickel: 5 cents
- Dime: 10 cents
- Quarter: 25 cents
Since we can't use a nickel, we need to find another combination of coins. Let's consider a dime and a 20 cent coin (which doesn't exist in reality, but let's assume it for this problem).
So, the solution is: 1 dime (10 cents) and 1 "20 cent" coin (20 cents). Together, they make 30 cents without using a nickel.
Remember, the key to solving this problem is to recognize that one coin is not a nickel, thus allowing us to use a nickel as the other coin.
