If the critical value is the only thing of interest, then this question is quite easy. Referencing a z table, you look up the percentage of interest: in this case, we must be 97.5% certain in order to accept the null hypothesis (significance level =2.5%. The number that corresponds to .9750 on the z table is 1.96. This is our critical value.

Your firm needs a computerized line-boring machine that costs $90,000 and requires $16,000 in maintenance costs for each year of
sladkih [1.3K]

Answer:

The aftertax salvage value of the machine is D) $10,134

Explanation:

Hi. first, we need to find out the book value of the machine at the selling date, that is 3 years from now, and the book value is as follows.

BookValue=90,000-90,000*0.3333-90,000*0.4444-90,000*0.1482=6,669

Since taxes are based on the profit you make by selling something, our profit is:

Profit=12,000-6,669=5,331

Therefore, our taxes are:

Taxes=5,331*0.35=1,866

So, the after tax salvage value of the machine is the money you received on the sale minus the taxes you have to pay, that is:

Salvage Value of the Machine = $12,000 - $1,866?= $10,134

That is option D)

Best of luck.

KengaRu [80]

Answer:

And, the other item values would remain the same

Now put these values to the above formula  

So, the value would equal to

= $7,280 + $1,120 + $6,200
