At $
$14/hour, working a full 40, 52 weeks/year (

), he'd be grossing $560, or $2160/4 weeks, or $2426/month. For total income tax, including fica (and assuming an employee, so possibly high), he'd ultimately owe about $3700 for the year ($0 state), or about $300/month, leaving $2100/month. So
1) no way he's paying $400/week for a car and 2) no way he saved $5k in a couple of months without additional income. Well, maybe on #2, I guess, if he found a $500/month apartment with utilities included, bc even phone, gas, food wouldn't eat the rest. If $200 car/
month, $80 phone, $200 gas (assuming he's driving for a living), $200 food, $200 insurance for car, no health insurance* and zero anything else, that leaves about $900/mo. So maybe (
NOT), since no reason to think he's making wise choices.
*Per
this, he would qualify for a subsidy but not free insurance at ft $14/hr.
