Please answer Question $7$

$1.$ Please take sales up to $$630,000$ and down to $$570,000($up by $5\%$ and down by $5\%)$ and record the new net present value numbers.

Sales up to $$630,000$ the net present value is $141,732$

Sales down to $$570,000$ the net present value is $3,451$

$2.$ Returning to the original numbers, please take disposition value up to $$525,000$ and down to $$475,000($up by $5\%$ and down by $5\%)$ and record the new net present value numbers.

Disposition value up to $$525,000$ net present value is $84,254$

Disposition value down to $$475,000$ net present value is $60,929$

$3.$ Returning to the original numbers, please take variable costs up for all years to $42\%$ and down to $38\%($up by $5\%$ and down by $5\%)$ and record the new net present value numbers.

$4.$ Returning to the original numbers, please take fixed costs up for all years to $$231,000$ and down to $$209,000($up by $5\%$ and down by $5\%)$ and record the new net present value numbers.

The net present value at $$231,000$ is $30,338\mathrm{.}63$

The net present value at $$209,000$ is $114,843\mathrm{.}9$

$5.$ Returning to the original numbers, please take the tax rate to up to $29\mathrm{.}4\%$ and down to $26\mathrm{.}6\%($up by $5\%$ and down by $5\%)$ and record the new net present value numbers.

Net present value tax rate $29\mathrm{.}4\%$ is $67,213\mathrm{.}64$

Net present value tax rate is $26\mathrm{.}6\%$ is $77,968\mathrm{.}85$

$6.$ Returning to the original numbers, please take the weighted average cost of capital for this project up to $10\mathrm{.}5\%$ and down to $9\mathrm{.}5\%($up by $5\%$ and down by $5\%)$ and rec$-$ord the new net present value numbers.

Capital $10\mathrm{.}5\%$ net present value is $52,806\mathrm{.}91$

Capital $9\mathrm{.}5\%$ net present value is $93,054\mathrm{.}75$

$7.$ From the answer to the prior six problems using the resulting range of outcome after making the $5\%$ changes to the variables, which variable has the greatest influence on the net present value of this project?
