What is the given projects present value

Question

Assignment:

Kohl Industries is considering a new project that would require an investment of $2,975,000 in equipment with a useful life of five years.  At the end of the five years the project would terminate and the equipment would be sold for its salvage value of $300,000.  The company's discount rate is 14%.  The project would provide net operating income each year as follows:  

Sales		$2,635,000
Variable expenses		1,100 000
Contribution margin		1,535,000
Fixed expenses:
Advertising, salaries, and other fixed costs:	$635,000
Depreciation	435,000
Total fixed expenses		1,070,000
Net operating income		$   465,000
