In your Fraud Examination Casebook with Documents textbook, read Case 3: Fraudulent Edits/Adjusting Journal Entries (pp. 53-60). Use the Excel template titled 203-Tonya Edits Template, which is available on the textbook’s Student Companion website. Submit your completed Excel file with responses to the following requirements: Data extractions are often difficult to read. So, convert the data extractions to a more understandable Excel schedule:Start with the data contained in the extraction labeled: Data Extraction 203 Tony Edits (Jan Feb Mar 2016).Schedule the specific information (for example, the date and amount of the original transactions [e.g., cash before disbursement], and the date and amount of the edited transactions [e.g., cash after the adjustment]) into the template.Calculate the differences, if any, between the original and the edited transactions.Then, compare the edited deposit transactions listed on the schedule to the deposit slips and bank statement provided with the second fraud case study in your textbook on pp. 155-178 (Check Fraud, Debit Card Fraud, Cash Larceny), in order to verify the amounts and the dates when the cash was actually deposited. Insert a check mark ‘√’ as evidence that the edited deposit amounts on the schedule agree with both the deposit slips and the bank statement.Identify in your Excel file the individual, monthly total number and dollars; the grand total number; and the dollars of the irregularities. Submit your completed Excel file with the answers to the above requirements (included in that Excel file only).

Production planning by Compaq

This is a problem that Compaq had faced illustrating the usefulness of linear optimization. Compaq introduced three new computer systems and two workstations: GP-1, GP-2, and GP-3, as well as WS-1 and WS-2. In the following table, we list the models, the list prices (in dollars), and the memory usage.

SystemPrice#256K BoardsGP-160,0004GP-240,0002GP-330,0002WS-130,0002WS-215,0001

The following dificulties were anticipated:

1. The in-house supplier of CPUs could provide at most 7,000 units, due to debugging problems.
2. The supply of 256K memory boards was limited to be no more than 8,000 units.

On the demand side, the marketing department established the following:

1. The maximum demand for the first quarter would be 1,800 for GP-1 system, 300 for GP-3 system, 3,800 for the whole GP, and 3,200 for the whole WS family.
2. Included in these projects were 500 orders for GP-2 system, 500 orders for WS-1, and 400 orders for WS-2 that had already been received and had to be fulfilled in the first quarter.

Compaq needed to make a production plan to consider all the above production limitations and demand projections and to maximize the revenue.

Linear Model for Compaq

The above problem can be reformulated as:

maxa∗60000+b∗40000+c∗30000+d∗30000+e∗15000

maxa∗60000+b∗40000+c∗30000+d∗30000+e∗15000

subject to the constraintsa+b+c+d+e<=7000

a+b+c+d+e<=7000

4a+2b+2c+2d+e<=8000

4a+2b+2c+2d+e<=8000

a+b+c<=3800

a+b+c<=3800

d+e<=3200

d+e<=3200

a<=1800

a<=1800

c<=300

c<=300

b>=500

b>=500

d>=500

d>=500

e>=400

e>=400

Also, keep in mind

maxc

T

x=−min(−c

maxcTx=−min(−cTx)

and minimization is the standard form of a Linear Program

Your task will be to solve the above problem, and maximize Compaq’s profits. Complete the Compaq function to maximize Compaq’s profits. Use the ConvertToStandardNormalForm function to help you. The matrices formed will be passed into a linear program solver to output the best solution.

Hint: Keep in mind that since this is a maximization problem, each value of matric c will have to be multiplied by -1 to bring it into standard form (please ignore the minus sign ‘-‘ outside the minimization expression, this will be accounted for in the solution).

In your implementation of the ALU there is no need to detect or handle overflow. However, it’s a good mental exercise to think about when/how an overflow might occur. When adding numbers with different signs, overflow cannot occur because the sum must be no larger than one of the numbers.

What happens when the signs of the numbers are the same? What happens in the case of subtraction?

How do we detect when an overflow does occur?

In your initial discussion post this week present an argument that proposes one change to our electoral system. (Please note, it will not be acceptable to say you do not think any change should be made.)

Several possible changes to could be:

• Eliminating the Electoral College
• Instituting required Voter ID
• Allowing felons to vote.
• Mandatory voting.
• Instituting an Election Day Holiday in which all Americans do not have to vote.
• You may also get creative and come up with your own original change!

Just be sure to go beyond just stating what change you want to make, but present an argument for why we should make that change and how that change would improve our electoral system.

In your argument, do not use words like “fair” or “good” or “better” or “equal” – how do you measure what is or is not “fair”? What if you and I have different definitions of what is or is not fair (these are not universal terms)?
