You just opened your store and for entertainment purposes, you choose to have a jelly bean machine. At the start, you have placed 520 jelly beans in the machine. When a customer loads in a coin, it will release 9 jelly beans.  - How many jelly beans will be left in the machine after 35 coins have been inserted?  - You set an alarm to your machine that when it has collected a particular amount of coins, it will alert you to refill the machine so it would not release fewer than the usual amount of jelly beans. How many coins would this be?
