Question

You and your friend were taking turns rolling a die when you thought of a game: If a one is rolled by either player, you pay your friend 50 cents, but when a different number is rolled, your friend pays you 10 cents. After 30 rolls, it turned out that you were even, and neither of you won anything.

How many times was a one rolled?
(PLEASE NO LINKS I REALLY NEED HELP)

Answer 1

6 times

Explanation:

1. There was no cents left

2. If you roll one and get 50 cents you have to minus it with rolling other number than 'one' 5 times because you'll get 10 minus if you roll another number (50 divided by 10 is 5)

3. If you divid 30 (The rolls) by 5 (amount of roll you have to roll if you get one)

4. It equals 6 and 6 is a even number

5. Sorry this was too confusing
