Answer:
$2500
Step-by-step explanation:
The maximum amount of payments allowed for payables per month is 36% of the gross monthly income. And here, the total payments that is made during the month is $600 and $300 for long term borrowings and PITI which is a long term commitment of making monthly payments.
So the total payments for settlement of long term obligations is $900 which is 36%.
So
Gross monthly Income = $900 / 36% = $2500.
