Tyrene Products manufactures recreational equipment. One of the company’s products, a skateboard, sells for $37. The skateboards are manufactured in an antiquated plant that relies heavily on direct labour workers. Thus, variable costs are high, totalling $25.90 per skateboard, of which 70% is direct labour cost. Over the past year the company sold 43,000 skateboards, with the following operating results: Sales (43,000 skateboards) $ 1,591,000 Variable expenses 1,113,700 Contribution margin 477,300 Fixed expenses 277,500 Net operating income $ 199,800 Management is anxious to maintain and perhaps even improve its present level of income from the skateboards. Required: 1a. Compute the CM ratio and the break-even point in skateboards. (Do not round intermediate calculations. Round your answer to the nearest whole number.) 1b. Compute the degree of operating leverage at last year's level of sales. (Round your answer to 2 decimal places.) 2. Due to an increase in labor rates, the company estimates that variable costs will increase by $1.85 per skateboard next year. If this change takes place and the selling price per skateboard remains constant at $37.00, what will be the new CM ratio and the new break-even point in skateboards? (Round your intermediate calculations and the "Contribution margin" answer to 2 decimal places and other answer to the nearest whole number. ) 3. Refer to the data in (2) above. If the expected change in variable costs takes place, how many skateboards will have to be sold next year to earn the same net operating income, $199,800, as last year? (Do not round intermediate calculations. Round your answer to the nearest whole number.) 4. Refer again to the data in (2) above. The president has decided that the company may have to raise the selling price of its skateboards. If Tyrene Products wants to maintain the same CM ratio as last year, what selling price per skateboard must it charge next year to cover the increased labor costs? (Do not round intermediate calculations. Round your answer to 2 decimal places. ) 5. Refer to the original data. The company is considering the construction of a new, automated plant. The new plant would slash variable costs by 20%, but it would cause fixed costs to increase by 92%. If the new plant is built, what would be the company’s new CM ratio and new break-even point in skateboards? (Round your intermediate calculations and the "Contribution margin" answer to 2 decimal places and other answer to the nearest whole number .) 6. Refer to the data in (5) above. a. If the new plant is built, how many skateboards will have to be sold next year to earn the same net operating income, $199,800, as last year? (Do not round intermediate calculations. Round your answer to the nearest whole number.) b-1. Assume that the new plant is constructed and that next year the company manufactures and sells 43,000 skateboards (the same number as sold last year). Prepare a contribution format income statement. (Input all amounts as positive values except losses which should be indicated by minus sign. ) b-2. Compute the degree of operating leverage. (Round your answer to 2 decimal places.)

Design and implement a Java program to create a GUI application that for calculating an employee’s travel expenses and reimbursement. The user will enter the following data:

∙ Number of days on the trip

∙ Amount of the airfare, if any

∙ Amount of car rental fees, if any

∙ Number of miles driven, if a private vehicle is used

∙ Amount of parking fees, if any

∙ Amount of taxi charges, if any

∙ Conference or seminar registration fees, if any

∙ Lodging charges, per night

Once all expanses are entered the program should then calculate what the employee’s reimbursement will be based on the following guidelines:

∙ $17 per day for meals

∙ Parking fees, up to $10.00 per day

∙ Taxi charges up to $20.00 per day

∙ Lodging charges up to $95.00 per day

∙ If a private vehicle is used, $0.27 per mile driven

Once calculated your program should display the following information:

∙ Total expenses incurred by the business person

∙ The total allowable expenses for the trip

∙ The excess that must be paid by the business person, if any

∙ The amount saved by the business person if the expenses are under the total allowed

The layout and formatting of your GUI interface should be creative, attractive and easy to use.

A 0.300 g sample of an aspirin tablet is used to prepare 100.0 mL of a stock solution by dissolving the tablet in 1 M NaOH then diluting with distilled water to the 100 mL mark of a volumetric flask.  A 0.30 mL sample of the stock solution is then transferred to a volumetric flask and diluted with 0.02 M iron(III) chloride to the 10.00 mL mark.  The tetraaquasalicylatoiron(III) complex concentration in this 10.00 mL sample is determined to be 4.3x10^-4M.  What is the percentage of acetylsalicylic acid in the original aspirin tablet?  Do not include the % sign in your answer.  For example, for a value of 100% enter 100.

Would really like a step by step answer. So i can understand the process.

I need this in C++ please. I started it, but I need to add Get Average, Get Row total, and Get highest in row to my source code. But I keep getting build errors. Can someone please help me with my code. I attached my code after the question. Thank you!

Write a program that create a two-dimensional array initialized with test data. The program should have the following functions:

getTotal - This function should accept two-dimensional array as its argument and return the total of all the values in the array.

getAverage - This function should accept a two-dimensional array as its argument and return the average of values in the array.

getRowTotal - This function should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row.

getColumnTotal - This function should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column.

getHighestInRow - This function should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the highest value in the specified row in the array.

getLowestInRow - This function should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the lowest value in the specified row in the array.

Demonstrate each of the function in this program.

my source code:

#include <iostream>
using namespace std;

const int ROWS = 4;
const int COLS = 5;

int getTotal(int [][COLS], int, int);
int getColumnTotal(int [][COLS], int, int);
int getLowestInRow(int [][COLS], int, int);

int main()

   int paArray[ROWS][COLS] = { {1, 2, 3, 4, 5}, {6, 7, 8, 9, 10}, {11, 12, 13, 14, 15}, {16, 17, 18, 19, 20} };

   cout << "The total equals " << getTotal(paArray, ROWS, COLS) << "\n";
   cout << "The total of column 3 is " << getColumnTotal(paArray, 3, ROWS) << "\n";
   cout << "The lowest in row 3 is " << getLowestInRow(paArray, 3, COLS) << "\n";

   system("pause");
   return 0;
         
}

int getTotal(int array[][COLS], int rows, int cols)
{
   int sum = 0;

   for (int row = 0; row < rows; row++)
   {
       for (int col = 0; col < cols; col++)
           sum += array[row][col];
   }

   return sum;
}

int getColumnTotal(int array[][COLS], int colToTotal, int rows)
{
   int sum = 0;
   for (int row = 0; row < rows; row++)

1. Marketing researchers have access to a great deal of information about consumers. What kinds of pressure might be brought to bear on a marketing researcher that might cause ethical dilemmas?
2. In 2005, a new federal law allowed consumers once-a-year free access to their credit reports. Many consumers who accessed their credit reports were surprised by the amount of information collected. What can marketers and marketing researchers do to minimize consumers' privacy fears?
3. What role do YOU (as the consumer) play in protecting your own privacy? In other words, what can you do to protect your privacy and what are ways that we give up access to our privacy?

You just bought a car and plan on driving to campus everyday. The university no longer offers free parking because of
the increase of parking needs. You have two options to buy a parking permit. A monthly permit costs $30 (due at the
end of each month), which is a pay-as-you-go plan and you pay every month. However, the auxiliary services offers
a discounted annual permit which only costs $250 (upfront). You may assume that the academic year (12 months)
starts from Sep 1st, and ends on Aug 31st.
(1) If you plan to use the permit for all 12 months of the year, what is your internal rate of return (implicit interest
rate)?
(2) If you are not going to be on campus during the summer break (two months, from Jun 1st to Aug 31st), is
your internal rate of return going to change? If so, how much?
(3) You heard that a partially used annual permit can be sold easily on the black market for $15×number of
remaining months unused, because the parking permit is not associated with the car plate and can be used by any car
in the same class. How this is going to change your internal rate of return?
