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 %
