Dragonfly, inc. is evaluating two possible investments in depreciable plant assets. the company uses the straightminusline method of depreciation. the following information is available: investment a investment b initial capital investment $ 105 comma 000 $ 158 comma 000 estimated useful life 10 years 10 years estimated residual value 0 $ 20 comma 000 estimated annual net cash inflow for 10 years $ 30 comma 000 $ 42 comma 000 required rate of return 12% 12% calculate the payback period for investment a. (round your answer to two decimal places.)

3.5 years

Explanation:

Investment A:

Initial capital investment = $105,000

Estimated useful life = 10 years

Estimated residual value = 0

Estimated annual net cash inflow for 10 years = $30,000

Required rate of return = 12%

Year                 Cash Flow                Accumulated Cash flow

  0                     -$105,000                         -$105,000

  1                        $30,000                          -$75,000

  2                       $30,000                         -$45,000

  3                        $30,000                         -$15,000

  4                        $30,000                           $15,000

Hence, at the end of 4th year the accumulated cash flow become positive. Therefore,

The pay back period for investment A = 3 +

                                                               = 3 + 0.5

                                                               = 3.5 years

answer; ///i believe the best answer is (d) replace negative self talk with positive self-talk;
