You will also have travel expenses (cost of travelling to work and back).
A bus ticket in the USA is probably 2-5 dollar. If you can even find a bus! Most people there travel by car. When you look for a job you will have make sure that you can get to the job by bus. A litre of milk in the USA might be 3-4 dollar. That is why $10 is not much. I am not sure how much a loaf of bread is: Maybe 2-3 dollar?

If you just want to make as much money as possible, then it would be better to go to Germany or England, than to go to the USA. Then you do not have to pay for a plane ticket. I think you would make more money there than you would in the USA, and it would be easier to live there and find a job. The USA is exciting but it is not a good place to be if you have no money...

If you still want to go to America, then it sounds like the easiest thing for you to do is to go to an area where lots of Russian speaking people live, and ask them for advice on how they found jobs.

The other option is to go into every restaurant, hotel and shop and say that you are looking for a job and can do anything. Remember in America, smile and look happy all the time Be positive. The more jobs you apply for, the sooner you will get a job.
