To explain BioCom's capital budgeting techniques, Jane has decided to present the cash flows from two recent proposals: the nano test tube project and the microsurgery kit project. All figures are in thousands of dollars:

Time of Cash Flow	Nano Test Tubes	Microsurgery Kit
Investment	($12,000)	($12,000)
Year 1	2,000	5,000
Year 2	3,000	5,000
Year 3	4,000	5,000
Year 4	5,000	5,000
Year 5	7,000	5,000

Compute the payback period for Nano Test Tubes project. Input your answer to the nearest tenth of a year. For example, if the answer is 2.17 years, input 2.2 into blackboard.
