Best possible way to lose weight with busy schedule?

How do I lose weight through exercising? I mean, I’m at school most of the time and the only time I have to exercise is on Sundays and mondays. We don’t have any equipment at home so what I’m planning to do is just exercise and eat the right kind of foods. But how will I lose weight if I only have 2 days of exercise? Any suggestions on what kind of exercises I should do? And what type of foods should I eat? I’m 17, girl, 110 pounds. I want to lose 10.

Please help me.
