A month expenses for a foreign student

Hello everyone,

Might be in Westchase 77082 -for a month starting mid June- for a medical internship ,and was wondering how much would be considered enough to bring with me for transportation (in general) and food (if I am going to buy 3 meals a day)?

About accomodation, what are the chances to find something that has a bed for less than 700$ all inclusive?

Is there anything else I should keep in mind (regarding expenses) during my visit?
