1. Santa Clara Electronics, Inc. of California currently exports 1,000,000 electric switches per year to the Argentina under an import agreement that expires in five years. In the Argentina, the imported switches are currently sold for peso equivalent of $75 per set. Santa Clara’s costs, including shipping, are $50 per set, and its current pre-tax profit is $25 per set. Similar costs and prices would occur in Argentine production. The market for this type of switch in the Argentina is stable (neither growing nor shrinking, and Santa Clara holds the major portion of this market.

   The Argentine government has invited Santa Clara to open an assembly plant so that imported switches can be replaced by local production. If Santa Clara makes the investment, it will operate the plant for 5 years and then sell the building and equipment to Argentine investors for $5,000,000. Santa Clara will be allowed to repatriate all net income and depreciation to the US at the end of each year. Santa Clara traditionally evaluates all foreign investments in U.S. dollar terms.  

   Investment:   Santa Clara’s anticipated outlay in 2020, expressed in US dollars and sufficient for the full five years, would be:

                         Building and Equipment                          $40,000,000

                         Working Capital                                            $10,000,000

                         Total Outlay                                              $50,000,000

              All investment outlays will be made in 2020, and all operating cash flows will occur at the end of years 2021 through 2025.

   Depreciation:           Building and equipment will be depreciated over five years on a straight-line basis to a $5,000,000 salvage value. At the end of the fifth year, the $10,000,000 of net working capital may be repatriated to the United States, as may the remaining net book value (salvage value) of the plant.

   Exchange Rates:           The Argentine peso (Ps) is currently at parity (US$1 = APs1) and is expected to remain at this level for the next five years.

   Sales: Locally manufactured switches will be sold APs75 each. Sales volume will remain 1,000,000 switches per year for the next five years.  

   Operating Expenses (current peso costs):

              Materials purchased in Argentina                 Aps30 per set

              Material imported from US parent               Aps20 per set

              Total variable costs                                    Aps50 per set

   The Aps20 purchase price for components sold by Santa Clara to its Argentine subsidiary consists of Aps15 of direct costs incurred in the United States and Aps5 of pretax contribution margin to Santa Clara. These peso costs (and profits) are expected to remain constant. Other operating costs include APs 5,000,000 in annual fixed operating costs by the Argentine subsidiary.

   Taxes:           Both the Argentina and the United States have a corporate income tax rate of 40 percent.

   Concessionary Loan: The Argentine government will assist Santa Clara’s local financing by provided a subsidized loan of 50 million peso loan. The loan will be a five-year amortizing loan (with annual payments) bearing an interest rate of 5 percent. Without the loan, Santa Clara’s normal borrowing rate would be 10 percent.

   Cost of Capital:           Upstate uses a 15 percent discount rate to evaluate all domestic and foreign projects.

              Estimate the value of the project’s cash accruing to the parent.

   		-$26,935,125
   		-$12,932,540
   		-$16,672,196
   		-$34,027,351
   		-$20,662,714

Recognizing the limitations of the generic truck weight data and conservative assumptions made during the calibration of live load factors for bridge rating, the AASHTO load and resistance factor rating (LRFR) manual for bridge evaluation provides sufficient flexibility and allows state agencies to adjust the live load factors based on their individual conditions and site-specific or state-specific information. This paper describes a reliability-based process that can be followed to perform such adjustments and illustrates its application using an example in which the procedure was followed during the calibration of a LRFR methodology for New York State bridges. This methodology is applied to the rating of existing bridges, posting of understrength bridges, and checking of permit trucks. The live load models used during the calibration are based on weigh-in-motion data collected from several representative sites. The LRFR live load factors developed using the proposed calibration process would provide uniform and consistent levels of bridge safety and reliability for the bridge classes and configurations targeted. The target reliability levels used during the calibration should reflect the experience gained by state bridge engineers from evaluation of existing bridges under current loading conditions.

Q1) Create a program that do the following:

1. Asks the user to enter n marks for n students, read the marks and the names and store them in a double linked list.

2. Write a method to find the largest mark and print the name of the student having that mark

3. Write a method to print the content of the list (name, mark)

4. Write a method to search the list for a given mark and prints the result

6. Insert 2 new students to the list (print the list before and after the insertion)

7. Delete any students with the first letter "D" in his name, (print the list before and after the deletion)

C++ language.

Suppose you are given a list of students registered in a course and you are required to implement an Linked List of student. Each student in the list has name, regNo and cGpa. You task is to implement following function related to Linked List.

insertStudent() : This function, when called will prompt user to enter his/her choice of insertion. The options are

1. Insert student at the start of linked list

2. Insert student at the end of linked list

3. Insert student before the student who name is entered

e.g if insertStudent(Student s, “Abrar”) is called, it will search student in the linked list with a name Abrar and then insert Student s (1st argument) before Abrar.

sortBycGpa( ) : When called, this function will sort all the students in the list based on CGPA.

display( ) : This function when called displays all the data of only those students whos cGPA are greater than the entered cgpa.

e.g. if display(3.5) is called, it will display all the students whos’ CGPA is greater than 3.5.

The Delaware River Joint Toll Bridge Commission increased the tool on the bridges on Route 22 and Interstate 78 from New Jersey to Pennsylvania from $0.50 to $0.75 in December. In November, the Route 22 bridge had 519,337 crossings and the Interstate 78 bridge had 728,002. Suppose that the price elasticity of demand for the Route 22 bridge was .2696 and that for the Interstate 78 bridge was 1.556. (Assume nothing other than the toll change occurred during the months that would affect consumer demand.)

a) How did the revenue from the two bridges change in December? (Be specific.)

b) Suppose that the Commission wanted to increase total revenue from each bridge and could set different prices for the two bridges. Should they be the same or different? If they are the same, should they increase? If they are different, how should they change the prices? (You don’t need to provide a specific price, but just the direction.)
