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' annual net income after taxes:

Annual salary: $33,300
Total taxes withheld: $4995 + $3463 = $8458
Annual net income: $33,300 - $8458 = $24,842

Now, let's calculate James' total annual costs for necessities:

Transportation: $230 x 12 = $2760
Cell phone bill: $75 x 12 = $900
Student loans: $210 x 12 = $2520
Rent: $625 x 12 = $7500
Utilities: $220 x 12 = $2640
Internet: $85 x 12 = $1020
Health insurance: $312 x 12 = $3744
Groceries: $250 x 12 = $3000

Total annual costs: $2760 + $900 + $2520 + $7500 + $2640 + $1020 + $3744 + $3000 = $23,084

Now, let's calculate James' monthly discretionary spending:

$24,842 (annual net income) - $23,084 (total annual costs) = $1758

Monthly discretionary spending: $1758 / 12 = $146.50

After all necessary expenses are accounted for, James has approximately $146.50 left each month for discretionary spending.
