Ajman Corporation adopted the dollar-value LIFO method of inventory valuation on December 31, 2017. Its inventory at that date was 220000 and the relevant price index was 100. Information regarding inventory for subsequent years is as follows.

Date Inventory at Current Prices    Current Price index

December 31, 2018    256800 107

December 31, 2019    320000    108

December 31, 2020    350000 120

A. What is the cost of ending inventory on December 31, 2018 under dollar value LIFO

B. What is the cost of ending inventory on December 31, 2019 under dollar value LIFO

C. What is the cost of ending inventory on December 31, 2020 under dollar value LIFO

A manager at Strateline Manufacturing must choose between two shipping alternatives: one-day freight and five-day freight. Using five-day freight would cost $175 less than using one-day freight. The primary consideration is holding cost, which is $10 per unit a year. One thousand items are to be shipped. Which alternative would you recommend? Explain.

Determine which shipping alternative would be most economical to ship 100 boxes of parts when each box has a price of $200 and holding costs are 40 percent of price, given this shipping information: overnight, $300, three-day, $200, six-day, $180.

1. Suppose you have a 10% bond that pays annual coupon and with mature in 10 years. The face value is $1,000, and the yield to maturity on a similar bond is 8%.         The bond is also convertible with a conversion price of 100. The stock is currently selling for $120. What is the minimum price of the bond?

2. You are considering a project that will require an initial outlay of $200,000. This project has an expected life of five years and will generate after-tax cash flows to the company as a whole of $60,000 at the end of each year over its five-year life. Thus, the free cash flows associated with this project look like this.

Given a required rate of return of 10% percent, calculate the IRR.

Overview

In this assignment you will apply what you have learned about standard deviation and normal curves to solve a number of problems, including finding the area under selected sections of a normal curve using z-scores, then solve a problem using normal distributions.

Part 1:

The weights of all one hundred (100) 9th graders at a school are measured, and it is found that the mean of all the measurements is 100 lbs., with a standard deviation of 15 lbs.   Explain how you would use this information to determine the percentage of students who weighed between 85 lbs and 115 lbs. Make sure your explanation includes the use of z-scores.

Part 2:

Using the example in part 1 above, answer the following questions in the same document you used to answer the questions from part 1. Make sure you show all the work required by the questions.

• What is the percentage of students who weighed between 85 lbs and 115 lbs? (Show calculations)
• What is the z-score of a student who weighed 105 lbs? (Show calculations)
• If a student weighed only 60 lbs, how many students out of the one hundred 9th graders would weigh more? (Hint: calculate the percentage 1st)

Part 3:

The following year, the 9th grade students are weighed again, and this time it is found that the mean of all weights is 108 lbs, and the standard deviation is 17 lbs. Answer the following questions, using the same document you used in parts 1 and 2 to show how you arrived at your answers.

Compare two students, one from the first class who weighed 98 lbs, and one from the second class who weighed 100 lbs.

• Which of the two students was heavier relative to their class? (Hint:compare z-scores)
• What percentage of students in the first class were heavier than the 98 lb. student?
• What percentage of students in the second class were heavier than the 100 lb. student?

4. The product y = Ax of an m × n matrix A times a vector x = (x1, x2, . . . , xn) T can be computed row-wise as y = [A(1,:)*x; A(2,:)*x; ... ;A(m,:)*x]; that is y(1) = A(1,:)*x y(2) = A(2,:)*x ... y(m) = A(m,:)*x Write a function M-file that takes as input a matrix A and a vector x, and as output gives the product y = Ax by row, as defined above (Hint: use a for loop to define each entry of the vector y.) Your M-file should perform a check on the dimensions of the input variables A and x and return a message if the dimensions do not match. Call the file myrowproduct.m. Note that this file will NOT be the same as the myproduct.m example. Test your function on a random 5 × 3 matrix A and a random 3 × 1 vector x. Compare the output with A*x. Repeat with a 3 × 6 matrix and a 6 × 1 vector and with a 3 × 6 matrix and a 1 × 6 vector. Use the command rand to generate the random matrices for testing. Include in your lab report the function M-file and the output obtained by running it.

Explain the errors in the C code that cause the output NOT to be -10. (Hint: There are 2 errors):

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
  
#define SIZE 5
void *threadFunc(void *arg);
int *changingVal;
int a[SIZE]; // Assume a[] = { 13444, 3320, 31020, 3302, 31313 };

int main() {
int i;
int min;
int * changeVal = malloc (sizeof(int*));
*changeVal = -10;
// Thread creation
pthread_t thread1;
pthread_attr_t attr;
pthread_attr_init(&attr);
  
for (i = 0; i < SIZE; i++) {
a[i] = rand();
printf("%d\n", a[i]);
}
min = a[0];
  
pthread_create(&thread1,&attr,threadFunc, &changeVal);

#pragma omp parallel for num_threads(1)
for (i = 1; i < SIZE; i++) {
if (a[i] < min) {
pthread_join(thread1, NULL);
#pragma omp critical

{
// compare a[i] and min again because min
// could have been changed by another thread after   
// the comparison outside the critical section
if (a[i] < min)
min = a[i];
}
}
}
printf("Min number found:\t%d\n", min);
}

void * threadFunc(void *arg) {
changingVal = (int*) arg;
a[3] = *changingVal;
pthread_exit(0);
}

2. South Africa will import more than it exports
3. South Africa’s balance of trade position will lead to more of a surplus position

1. The Australian dollar depreciated in value
2. Interest rates increased in Australia
3. Interest rates decreased in Australia
4. The Australian dollar appreciated in value

3. BRL is the symbol for the Brazilian Real, the name of Brazil’s currency. USD/BRL 4. A Honda CTX700 motorcycle sells for $7,400 in the U.S. Is the Brazilian Real over or undervalued?

Please answer all questions, need to check my answers.

I'm very confused about this whole import & export concept and how it is affected by rising or declining interest rates. If you could please explain it to me I'd really appreciate it

2. Accounting procedures allow a business to evaluate their inventory costs based on two methods: LIFO (last in first out) or FIFO (first in first out). A manufacturer evaluated its finished goods inventory (in $000s) for five products with the LIFO and FIFO methods. To analyze the difference, they computed FIFO − LIFO for each product. We would like to determine if the LIFO method results in a lower cost of inventory than the FIFO method.
