1. The following represents demand for widgets (a fictional product):

Q_D = 125,568 – 220P - 0.0001M + 0.5P_R

where P is the price of widgets, M is income, and P_R is the price of a related (fictional) good, the wodget. Supply of widgets is determined by

Q_S = 200P – 10,800

1. Determine whether widgets are a normal or inferior good, and whether widgets and wodgets are substitutes or complements.
2. Assume that M = $55,000 and P_R = $275. Solve algebraically to determine the equilibrium price and quantity of widgets.
3. Generate a supply/demand graph in Excel. Be sure that P is the vertical axis and Q the horizontal. Does the graphical equilibrium correspond to your algebraic equilibrium?
4. Now assume two events occur: demand changes such that the intercept in the demand equation rises to 145,568 and supply conditions change such that

Q_S = 290P – 27,700. Solve algebraically for the new equilibrium price and quantity of widgets after these two changes.

We are evaluating a project that costs $588,000, has an eight-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at $70,000 units per year. Price per unit is $36, variable cost per unit is $20, and fixed costs are $695,000 per year. The tax rate is 35 percent, and we require a return of 15 percent on this project.

a. Calculate the accounting break even point.

b. Calculate the base-case cash flow and NPV. What is the sensitivity of NPV to changes in the sales figure? Explain what your answer tells you about the a 500-unit decrease in projected sales.

c. What is the sensitivity of OCF to changes in the variable cost figure? Explain what your answer tells you about a $1 decrease in estimated variable costs.

Suppose, the government of Australia incurs a budget deficit of $50 billion due to increased government spending in 2020 as result of Covid 19. Because of this, the government borrowing in 2021 increases by the same amount.

a) Show this development using a graph representing the market for loanable funds for Australia . Explain in writing the effect of this on interest rates. .

Answer Graph

Effect on interest rate (1 mark)

b) Compare the size of equilibrium changes in 1) investment, 2) public saving, 3) private saving and 4) national saving (public saving + private saving) with $50 billion increase in borrowing. Compare the changes (increase/decrease) in these variables indicating same, less or more than the $50 billion.

Answer:

c) Will the equilibrium quantity of national savings change by more or less than the initial change in public saving? Explain your answer (in 50 words or less)

Answer:

Demand and Supply in Perfect Competition Cows are munching down zucchini, yellow squash and cabbage that Southern Valley Fruit and Vegetable farms grew and picked for restaurants and other institutions. It’s one way the company is trying to make use of the glut of south Georgia vegetables caused by the closure of dining spots, schools and other big buyers. South Georgia farmers ship food from Florida to Canada, but the closures cost them 40- to 50% of their market. Growers are caught between being unable to sell all their crop and selling what they can in a flooded market with dropping prices.

1. Draw a demand and supply diagram that illustrates the changes taking place in the vegetable market. Explain any changes you draw.

2. Assume vegetable farms operate in a perfectly competitive market. Draw a cost and revenue diagram that shows the effect on farms profits of “dropping prices”

Tom was recently diagnosed with a tumor in the posterior aspect of his spinal cord at the level of C6 that has resulted in a C5 incomplete spinal cord injury with changes in sensation. Based on the location of the tumor: 1. What ascending spinal tract(s) have been affected? 2. What types of sensation have been affected and what types remained intact? (i.e. temperature, pain, proprioception, etc.) 3. Where on Tom’s body will the sensory deficits be present? Use specific dermatomes. After Tom undergoes surgery to remove the tumor, he presents to inpatient rehabilitation to begin therapy. 1. Given the sensory changes you discussed above, what activities would be difficult for Tom to perform? (i.e. ADLs, functional mobility…) 2. If you were Tom’s occupational therapist, what interventions would you recommend to help with his recovery

Determination of an Equilibrium Constant

1.    What is meant by a reversible reaction?

2.   True or False :       The numerical value of the equilibrium constant for                        a given reaction only changes if the temperature
                   changes.

3.   Which component of the reaction mixture was it that was titrated with
   sodium hydroxide?

   A.   Acetic acid           B.   Isopropyl alcohol

   C.   Water               D.   Phenolphthalein

4.   Why was it necessary to wrap your rubber stopper in plastic wrap?

5.   Why was it necessary to titrate a blank sample solution, that is, a sample
   of distilled water which contain only sulfuric acid?

6.   List two advantages of using a buret for measuring reaction volumes as
opposed to maybe a graduated cylinder. (Precision and accuracy are not exceptable answers)

7.   What is a catalyst and how and why was a catalyst needed in this
   experiment?

8.   When would you want to use a pipet instead of a buret in an experiment?

1. How could a bank utilize an interest rate swap, if it has a classic “floating rate deposits as liabilities and fixed rate loans as assets” balance sheet? What would it choose to pay in a swap, what would it choose to receive?

A. It would choose to pay fixed and receive floating

B. It would choose to receive fixed and pay to float

2. The reason the bank in question 1 might seek to enter an interest rate swap is that:

A. changes in interest rates cause its liabilities reset more quickly than its assets

B. changes in interest rates cause its assets to reset more quickly than its liabilities

3. The bank in question 1 might seek to mitigate fixed rate asset exposure by investing in adjustable-rate mortgages or floating rate commercial loans (T or F)

Solano Company has sales of $800,000, cost of goods sold of $520,000, other operating expenses of $35,000, average invested assets of $2,350,000, and a hurdle rate of 11 percent. 2. Several possible changes that Solano could face in the upcoming year follow. Determine each scenario’s impact on Solano’s ROI and residual income. (Note: Treat each scenario independently.) (Enter your ROI percentage answers to 2 decimal places, (i.e., 0.1234 should be entered as 12.34%.)) 2. Several possible changes that Solano could face in the upcoming year follow.

Create a Netbeans project called LineNumbers

The program should do the following:
–Ask the user for how many lines of text they wish to enter

–Declare and initialize an array of Strings to hold the user’s input

–Use a while loop to prompt for and read the Strings (lines of text) from the user
at the command line. Typically, this would be a 'for' loop since we know the number of times to execute the loop based upon the number supplied by the user, but for the purposes of this assignment use a 'while' loop to practice.

–After the Strings have been read, use a for loop to step through the array of
Strings and concatenate a number to the beginning of each line and store them back in to the array:

"This is" changes to "1 This is"

"The first day" changes to "2 The first day"

and so on…

–Finally, use a **for each** loop to output the Strings (numbered lines) to the command line

You manufacture two products, A and B, each of which you sell for $1 profit. Product A requires 5 blobs and 3 globs, and product B requires 3 blobs and 5 globs. Your supplier has 120 blobs and 120 globs available.

Use the Excel Solver (or graphical analysis) to answer the following questions.

9. If the profit on B increases to $2, can you increase profit by trading 30 blobs for 30 globs?

10. As the profit on B changes from $1 to $1.66, does your business decision concerning product mix stay the same?

11. As the profit on B changes from $1.66 to $1.67, does your business decision concerning product mix change?

12. If the profit for A and B increase to $2 each, will you want to trade excess blobs for globs?
