   In March 2018, Blue Devil Company realized that they had overstated their December 2016 ending inventory by $15,000. If the reported Net Income for 2017 was $125,000, what should be the correct Net Income for 2017?

   
   

Why is the answer 140,000? If ending inventory is overstated by 15k wouldnt cost of goods sold be understated by 15k making Net income be overstated by 15k, therefore subtracting 15k from the net income to correct the error?  why would one add 15k to Net income to get 140k?
