Increase a column of values by a percentage

Hi, I want to increase all the prices in a table by 10%. This is what I use to increase the prices by a simple addition:

UPDATE table_name
SET `Price`= `Price`+10

I am assuming I need to combine an SQL statement with some PHP like this:

$percentage = 10;
$whatever = `Price` - (($percentage/100)*`Price`);

But I do not know how. Can anyone help?

Try UPDATE table_name
SET `Price`= `Price`*110/100

Try UPDATE table_name
SET `Price`= `Price`*110/100

This works for me. Many Thanks.
