All this depends on business rules, but yes, I would expect a price column
in a Orderline table. That gives the price for that specific order. The customer may have gotten a discount. And more importantly, if you change the
price for the product, you don't want that to affect old orders.

Although, in your example I would store 10 in the Price column in the
Orderline table. If it was called Amount I would store 30. But that's more of a language issue.
