Is it possible to lose 10 pounds in two months?

I'm 17, five foot one and weigh 105lbs. So far I have been running nonstop everyday for 30 minutes and eating all healthy food plus monitoring my calorie intake. I have two months till school starts and I'm wondering if this is a possible goal that I can achieve?? My problem area is my thighs and my upper arms. Also how many calories should I consume each day to meet my goal?
