$12-51$ Basic Capital Budgeting Techniques; Uneven Net Cash Inflows; Taxes; MACRS Depreciation Use the data in Problem $12-50$ for Bob Jensen Inc. and MACRS. The asset qualifies as a five$-$year property.

Required Compute the following for the proposed investment:

$1.$ Its payback period $($in years$)$ under the assumption that the cash inflows occur evenly throughout the

year. Round your answer to $1$ decimal place $($e$.$g$.,4\mathrm{.}341$ years $=4\mathrm{.}3$ years$).$

$2.$ Its accounting $($book$)$ rate of return based on $($a$)$ the initial investment and $($b$)$ an average investment $($calculated here as a simple average of the $10$ average annual book values; for each year, the average book value is the sum of the beginning$-$of$-$year and end$-$of$-$year book values, divided by two; note; the average book value for each of the last four years is $$0).$ Round both answers to $1$ decimal place $($e$.$g$.,13\mathrm{.}417\%=13\mathrm{.}4\%).$

$3.$ Its estimated net present value $($NPV$).$ Use the built$-$in NPV function in Excel; round your answer to the nearest whole dollar.

$4.$ Its internal rate of return $($IRR$).$ Use the built$-$in IRR function in Excel; round your answer to $1$ decimal

place $($e$.$g$.,5\mathrm{.}491\%=5\mathrm{.}5\%).$

$5.$ Its modified internal rate of return $($MIRR$),$ rounded to $1$ decimal place.
