Trying to lose weight before school starts?

-Hey! I have a little more than a month before school starts and I really want to tone up and lose weight before then... Currently, I am 5 foot 6 and 110 lbs (around average weight). I am 17 and a girl!

How much weight do you think I could lose before September? Currently, I maintain my current weight by eating 1700-2300 calories a day and working out 2-3 times a week. I manage to maintain my current weight while still eating a lot!!

What plan should I go on to lose 5-10 pounds by school time??! THANKS!!Decrease your calorie intake by 1000 per day, and you will lose 2 pounds per week.
