Recent technology has made possible a computerized vending machine that can grind coffee beans and brew fresh coffee on demand. The computer also makes possible such complicated functions as tracking the age of an item and then moving the oldest stock to the front of the line, thus cutting down on spoilage. Easy Snack Inc. has estimated the cash flows in thousands of dollars over the products' six-year useful life, including the initial investment, as follows:
n Net Cash Flow
0 - $200,000
1 $80,000
2 $180,000
3 $180,000
4 $180,000
5 $100,000
6 $30,000
