On January 2, 2015, the S. H. Park Company (Park) installed a new $84,000 special molding machine for producing a new product. The product and the machine have an expected life of three years. The machines expected disposal value (amount machine can be sold for) at the end of three years is zero. S. H. Park Company paid cash when the equipment was delivered. Park paid for this machinery via bank transfer. On January 3, 2015, Kimiyo Lee, a salesperson for BT Machine and Tool (BT), tells Park: “I wish I had known earlier of your purchase plans. I can supply you with a technically superior machine for $99,000. Lee indicated the machine just purchased can be sold for $16,000. Lee guaranteed that there machine will save S. H. Park $35,000 per year in cash operating costs. This machine will have no disposal value at the end of three years.” Assume all costs are cost of sales. Park examines some technical data. Park is confident of Lee’s claims. However, Park contends, “I’m locked in now. My alternatives are clear: (a) disposal will result in a loss, (b) keeping and using the ‘old’ equipment avoids such a loss. I have brains enough to avoid a loss when my other alternative is recognizing a loss. We’ve got to use that equipment until we get our money out of it.” The annual operating costs of the old machine are $60,000 all paid in cash. This does not include depreciation. The new machine operating costs will be $25,000 which will be paid in cash. Sales, all in cash, are projected to be $850,000 per year. Annual cash expenses related to sales are $350,000 for material, $250,000 for labor and $150,000 for other operating expenses regardless of this decision. Assume that the equipment in question is the company’s only fixed asset. Ignore income taxes and the time value of money. Any cash payments for the machines occurred in 2015 coinciding with the purchase of the equipment. Should Park dispose of the “old-old” machine (stay the course) or should Park acquire new machine’s (New-New) from Lee? Using the template, prepare income statements as they would appear in each of the next three years under both alternatives. Assume straight-line depreciation over a three year period. What is the cumulative increase or decrease in net income for the three years for each alternative? Prepare statements of cash receipts and disbursements as they would appear in each of the next three years under both alternatives. Assume straight-line depreciation over a three year period. What is the total cumulative increase or decrease in cash for the three years for each alternative? If you were the sales person (Kimiyo Lee), how would respond to Mr. Park so as to get him to purchase your product? Using the provided information, if possible, prepare an alternative analysis which provides a similar result. Regardless of the financial analysis, what factors which effect or influence the decision to replace the equipment or stay with old (new) machine

prove A(A+B) = A using truth table

do you think the way classical economics models individual decision making (through utility maximization) is flawed and should be altered? If so, how?

In reaching her destination, a backpacker walks with an average velocity of 1.05 m/s, due west. This average velocity results, because she hikes for 5.66 km with an average velocity of 2.54 m/s due west, turns around, and hikes with an average velocity of 0.403 m/s due east. How far east did she walk (in kilometers)?

On January 1, 2018, the general ledger of Freedom Fireworks includes the following account balances:

The following information is available on January 31, 2018.

1. Depreciation on the building for the month of January is calculated using the straight-line method. At the time the building was purchased, the company estimated a service life of 10 years and a residual value of $26,000.
2. The company estimates future uncollectible accounts. The company determines $5,000 of accounts receivable on January 31 are past due, and 50% of these accounts are estimated to be uncollectible. The remaining accounts receivable on January 31 are not past due, and 2% of these accounts are estimated to be uncollectible. (Hint: Use the January 31 accounts receivable ending balance shown in the general ledger to start your calculations.) Record the estimated bad debt expense.
3. Unpaid salaries at the end of January are $28,100. (Recognize that salaries are owed, but have not been paid yet.)
4. Accrue income taxes at the end of January are $10,000. (Recognize that income taxes are due, but have not been paid yet.)

I asked this question before, but I'm wondering if there are any other ways to do this problem. My exam will be similar to this, so I'm looking for more examples to study with. Thank you!

For this Java program, you will write two classes: GradeCalculator and GradeCalculatorDriver.

In the GradeCalculator class, compute the final average and letter grade for a particular student.

The final average is calculated according to the following rules:

1) There are ten exams scored out of 100 points

2) The lowest exam score is not included in the calculation of the final average

3) The highest exam score is not included in the calculation of the final average

4) An average of 91-100 is an A

5) An average of 81-90 is a B

6) An average of 71-80 is a C

7) An average of 61-70 is a D

8) An average of 0-60 is an E

The GradeCalculator class must include the following methods:

1) A method to compute and return the highest score

2) A method to compute and return the lowest score

3) A method to compute the sum of all the scores

4) A method to compute the final average

5) A method to determine the letter grade

In the GradeCalculatorDriver class, include a main method that asks the user for the student’s name and their ten exam grades, reads the grades, calculates the letter grade and prints it. This process should be repeated until the user enters N.

For example, a run of the program might look something like this:

Welcome to Score Calculator

Want to compute a final average? Y

Please enter the student’s name: Sara Smith

Please enter test scores all on one line separated by one or more spaces.

The final score for Sara Smith is 100.

The letter grade for Sara Smith is A.

Want to compute another final average? N
