I need help with this problem

Sweet Catering completed the following selected transactions during May 2016:

• May 5: Received and paid electricity bill, $70
• May 9: Received cash for meals served to customers, $1,770
• May 23: Served a banquet on account, $1,800
• May 31: Accrued salary expense, $3,270
• May 31: Recorded prepaid insurance expired, $110

If Sweet Catering had recorded transactions using the Accrual method, how much net income (loss) would they have recorded for the month of May? If there is a loss, enter it with parentheses or a negative sign.
