553658 MYSQL Help

Below is a generic example of what I need. I have DB named [store] with a table named [price] with a 2 fields named [product] and [msrp], There are about 200 rows in the table. I would like to execute a update query to update the field [msrp] on each row to a new precentage. ( like increase the [msrp] by 10 percent ) What would be the php code to do this?
