The Alien Mugging

Just after cashing his paycheque at his local credit union, Jim was abducted by space aliens. They took Jim into their space ship and stole most of his money before setting him down on earth again.

Jim was left with only a small portion of the money he had just after cashing his paycheque. Jim's paycheque was ten times his age in dollars, and he was left with only one-tenth of his age in dollars. If the space aliens took $396 dollars, how old is Jim?
