Doubt about SELECT

Hi, i'm kinda new on postgresql, so i have a doubt, i'm trying to make a
query look like this:

I feel like it is something so simple, show the "SUM(price_serv) AS total"
on a new line, but i just can't find the way. I've read the postgresql
manual over and over and i couldn't find anything there.

I'm sure you guys can help me.
