How many calories should I BURN in order to reach my goal

I've got a dance competition in 70 days. I'm a little bit overweight. 5 foot 7 and 160 lbs, about a size 6 or 8
I'd like to lose 20 lbs in 70 days, maybe reach a size 4 or 6.
I know all about eating healthy and to cut out crap, I've been doing it for years.
I eat anywhere from 1,200-1,400 calories a day currently.


My question is how many calories should I burn a day to lose the weight in time?
