I know this has been posted before with different numbers and I can not get it to work. Can you please help me figure out the operating cash flow.

NPV. Grady Precision Measurement Tools has forecasted the following sales and costs for new GPS system annual sales of 45,000 units at $17 a unit, production costs at 39% of sales price, annual fixed costs for production at $180,000. The company tax rate is 30%. What is the annual operating cash flow of the new GPA system? Should Grady Precision Measurement Tools add the GPS system to its set of products? The initial investment is $1,400,000 and is depreciated over six years (straight line) and will be sold at the end of five years for $380,000. The cost of capital is 10%
