How much fat do you think ill lose with this plan?

First. Im 20 years old, female, 5'6" 126 lbs. And an adrenal body type. I dont care to lose weight, but id like to lose fat and tone up? What kind of results do you think I will have doing the following: yoga for an hour each time 2 days a week, zumba for an hour 1 day a week, and doing a step aerobics class for an hour 1 day a week. Plus waiting tables for 5 hour shifts at a busy restaurant 4 days a week. And do you have any other recommendations for me? I need to get in shape for a very important trip in july and also for summer bc I model bikinia over summer and ive gotten somewhat out of shape. Im looking for a slightly toned, lean look. Any help is greatly appreiated! Thanks!!! :)
