Life in the US is REALLY expensive! My family of 5 spends around US$400 on food a month, so that equates to around US$80 per person - a real small portion of our monthly expenses. We eat out around twice a week, which costs the
whole family around US$ 15 a meal (not per person!).
Coming from a very well-to-do family (on par with American standards), I cost my parents just US$180 a month:
1. I don't pay for school as schooling is subsidized by the government. US$0.
2. I wear second-hand clothes from my mother (we share same cloth sizes, and she's incredibly up-to-date with fashion

). US$0.
3. I don't own a mobile phone because no one calls me so I don't have any phone expenses. US$0.
4. Food. US$80
5. DVDs. US$15
6. Unfortunately, there aren't any good libraries where I live, so I spend quite A LOT on books. US$50
7. I share the internet with my father, and my young brother uses it for games. However, the internet connection is very expensive and costs US$40 a month. My share of the expense: US$25.
8. Household electricity and gas, and also car expenses costs US$40 a month. My share of the expense: US$10.
Of course, I'm only 15 so the expenses are going to grow as I get older. By the time I'm in university, I'll be costing my parents US$30,000 annually, unless I manage to qualify for financial assistance. I hope to be working part-time by then.
