Here is a sales report from one of our account.

We're proposing games to purchase at $2.99, $4.99 or $6.99 and a subscription offer for 2 new games every month at $4.99 per month.

Each line of the table represents a transaction, it could be a purchase (game or a new subscription), a recurring charge (every renewal of the subscription offer) or a refund

Please create a table to present all the number of transaction and total revenues net per type of transaction. In the same table, identify clearly the refunds as negative revenues.
