I need help with this problem:



Your firm has net income of $325 on total sales of $1,400. Costs are $770 and depreciation is $130. The tax rate is 35 percent. The firm does not have interest expenses. What is the operating cash flow?



A:$630

B:$325

C:$500

D:$825

E:$455



I did this problem using a financial calculator, excel, and a regular graphing calculator. I keep on getting choice C which is 500 but the homework system that i am using keeps telling me im wrong. Can someone please help me with this.
