Answer:
$7,000
Explanation:
Depreciation: The depreciation is an expense that shows a reduction in the value of the fixed assets due to tear and wear, obsolesce, usage, time period, etc. It is shown on the debit side of the income statement. It is a non-cash item that does not affect the cash balance.
The computation of the depreciation expense for 2017 is shown below:
= (Original cost - residual value) ÷ (useful life)
= ($78,500 - $8,500) ÷ (10 years)
= ($70,000) ÷ (10 years)
= $7,000
In this method, the depreciation is same for all the remaining useful life
Do you just need like a study guide with everything wrote down and organized or do you need it in a different way? I might be able to help :)
The complete question is as follows:
The admission directory of Big City University has a novel idea. He proposed using the IQ scores of current students as a marketing tool. The university agrees to provide him with enough money to administer IQ tests to 50 students. So the director gives the IQ test to an SRS of 50 of the university’s 5000 freshman. The mean IQ score for the sample is xbar=112. The IQ test he administered is known to have a σ of 15. What is the 95% Confidence Interval about the mean? What can the director say about the mean score of the population of all 5000 freshman?
Answer: The 95% confidence interval about the mean is
.
The director can say that he is 95% confident that the mean IQ score of the 5000 freshmen lies between 107.84 and 116.16.
We follow these steps to arrive at the answer:
Since the population standard deviation of the IQ test is known, we can use the Z scores to find the confidence interval.
The formula for the confidence interval about the mean is:

In the equation above, X bar is known as the point estimate and the second term is known as Margin of Error.
The Critical Value of Z at the 95% confidence level is 1.96.
Substituting the values in the question in the equation above we have,



Answer: $880.57
Explanation:
Assuming Par value of bond is $1,000.
Value of bond = (Coupon * Present value interest factor of annuity, no. years, required return) + Par Value/ (1 + required return)^ no. of years
Coupon = 5% * 1,000 = $50
Value of bond = (50 * 5.9713) + 1,000 / (1 + 7%)⁸
= 298.565 + 582
= $880.57
Answer:
a. 7,900
b. 10,100
Explanation:
As for the provided information,
We know at break even point taxes shall be = 0 as there are no profits and no losses.
a. At break even: = 
Fixed Cost = $308,100
Contribution per unit = Selling price - Variable cost = $79 - $40 = $39
Therefore, break even units = 
b. In case the company wants a profit of $51,480 after tax @ 40% then,
Earnings before taxes =
= $85,800
Therefore, number of units = 
=
= 10,100
