Jacob recently graduated from college and is starting a new job where he will have to commute to work by car. He shares an apartment with a roommate and his share of rent and utilities comes to $700 per month. His other necessary monthly expenses include $350 per month for food, $350 per month in student loan repayments and $200 per month in personal expenses. His take-home pay from work is $2,000 per month. If auto insurance and repairs for his new vehicle are expected to be $200 per month, what is the greatest amount he can commit for a monthly vehicle payment with no safety margin?
