How much money is left each month for discretionary spending after all necessities are accounted for? Round your answer to the nearest cent, if necessary.

First, let's calculate James's total annual taxes withheld:

$3773 + $3293 = $7066

Now, let's calculate James's total annual costs for transportation, cell phone bill, student loans, and rent:
$190 + $65 + $240 + $400 = $895 per month
$895 * 12 = $10,740

Now, let's calculate James's total annual costs for utilities, internet, health insurance, and groceries:
$260 + $100 + $336 + $200 = $896 per month
$896 * 12 = $10,752

Now, let's add all of James's annual costs together:
$7066 + $10,740 + $10,752 = $28,558

Now, let's subtract James's total costs from his yearly salary to find out how much money is left each month for discretionary spending:
$34,200 - $28,558 = $5,642

Finally, let's divide the remaining amount by 12 to find out how much is left each month for discretionary spending:
$5,642 / 12 = $470.17

Therefore, James has approximately $470.17 left each month for discretionary spending after all necessities are accounted for.
