It means that you need to return two variables to the caller of the routine or program. The selected product is the first item, and the coins/notes in change the second item.

Also you have tagged this question Java and PHP, but which language are you writing it in?

The user inputs a number of coins, which are mixed denominations. He selects a product which has a price.
You task is to check the total he entered against the product price and if he has paid enough subtract the price from the input total, and work out the minimum number of coins to return.
So if he enters two quarters, that's 50c. He selects a Pepsi, so you owe him 15c change. The smallest number of coins is a dime and a nickel.

Get the idea now?

How is it possible ? Never saw a vending machine ?
When you buy something in a machine, do you understand if the machine will give you change and how much ?
that is question 3.

The 1 vote is basically ok, but without a comment it is basically not ok. So I try to compensate with my small 5
