The following data have been collected by capital budgeting analysts at Halda, Inc. concerning an investment in an expansion of the company's product line. Analysts estimate that an investment of $210,000 will be required to initiate the project at the beginning of 2016. Estimated cash returns from the new product line are summarized in the following table; assume that the returns will be received in lump sum at the end of each year.

Year	Amount of Cash Return
2019	$	90,000
2020		80,000
2021		70,000
2022		60,000

The new product line will also require an investment in working capital of $30,000; this investment will become available for other purposes at the end of the project. Salvage value of machinery and equipment at the end of the product line's life is expected to be $20,000. The cost of capital used in Hilda, Inc.'s capital budgeting analysis is 10%. (a.)
