The capital investment committee of Iguana Inc. is considering two capital investments. The estimated operating income and net cash flows from each investment are as follows:

Year Robotic Assembler

$1$ $$35,000$ $$65,000$ $$21,000$ $$51,000$

$320,00050,00021,00051,000$

$415,00045,00021,00051,000$

Total $$105,000$ $$255,000$ $$105,000$ $$255,000$

Each project requires an investment of $$150,000.$ Straight$-$line depreciation will be used, and no residual value is expected. The committee has selected a rate of $12\%$ for purposes of the net present value analysis.
