Explanation:

Computation of net income and net profit margin

Revenues   ( $   900 + $ 1,700 )                                                     $ 2,600    

Expenses ($ 200 + $ 1,200 + $ 100 )                                             $ 1,500

Net Income                                                                                      $ 1,100    

Net profit margin = Net income / Revenues

Net Profit margin   = $ 1,100/ $ 2,600 =                                          42.3 %  

The other entries for collections made on Feb 04 for services to be performed next month and the purchase of supplies to be used in the future are not to be considered in revenues and expenses as they do not pertain to the current month
