(Ignore income taxes in this problem.) Baldock Inc. is considering the acquisition of a new machine that costs $361,000 and has a useful life of 5 years with no salvage value. The incremental net operating income and incremental net cash flows that would be produced by the machine are: Incremental Net Operating Income Incremental Net Cash Flows Year 1 $68,000 $151,000 Year 2 $74,000 $150,000 Year 3 $85,000 $178,000 Year 4 $48,000 $150,000 Year 5 $90,000 $152,000 Assume cash flows occur uniformly throughout a year except for the initial investment. The payback period of this investment is closest to: 3.3 years 5.0 years 4.7 years 2.3 years
