Answer 2

hmm.... quite a choice you've made!!

Norway is known as one of the most expensive countries in the world! i cant tell you exactly the cost of rent and so on, but it is expensive! Food is expensive, travelling is expensive......

you might spend around 200 euros/month for food if you are good at shopping and know how to save money.
