I'm 5'4" and 149 lbs. I want to lose 10-15 lbs in the next 3 months. My diet is good (no fast food, lots of water, etc.) But just for a guideline, about how many calories should I be getting per day to reach this goal?

Exercise is the main part I need help with. I can't get a gym membership right now, or buy any expensive equipment, so that's not an option. So basically I have running, basketball, biking, jump roping, and other stuff like that available. How much of each of those specific activates should I do to burn a good amount of fat each day?
