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 you
r 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)
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)
