I am an 18 year old female, 180 pounds, trying to get down to 130, I am 5'5". What would be an appropriate calorie intake per day?

Depends. First off, your target may be too low. Any weight under 150lb will give you a normal bmi and be healthy. Remember that healthful eating, including lots of fresh vegetables and minimal animal fats, is best. Depending on your activity level, 1200-1500 kcal is a reasonable guess, but check out the nih healthy eating site for more detailed advice: http://tinyurl.Com/7xu8qzr.
