- Write a program that reads a bank account balance and an interest rate and displays the value of the account in ten years. The output should show the value of the account for three different methods of compounding interest: annually, monthly, and daily. When compounded annually, the interest is added once per year at the end of the year. When compounded monthly, the interest is added 12 times per year. When computed daily, the interest is added 365 times per year. You do not have to worry about leap years; assume that all years have 365 days. For annual interest, you can assume that the interest is posted exactly one year from the date of deposit. In other words, you do not have to worry about interest being posted on a specific day of the year, such as December 31. Similarly, you can assume that monthly interest is posted exactly one month after it is deposited. Since the account earns in- terest on the interest, it should have a higher balance when interest is posted more frequently.…arrow_forwardCan answer the task below?arrow_forwardWrite a program that can be used to calculate the federal tax. The tax is calculated as follows: For single people, the standard exemption is $4,000; for married people, the standard exemption is $7,000. A person can also put up to 6% of his or her gross income in a pension plan. The tax rates are as follows: If the taxable income is: Between $0 and $15,000, the tax rate is 15%. Between $15,001 and $40,000, the tax is $2,250 plus 25% of the taxable income over $15,000. Over $40,000, the tax is $8,460 plus 35% of the taxable income over $40,000. Prompt the user to enter the following information: Marital status If the marital status is “married,” ask for the number of children under the age of 14 Gross salary (If the marital status is “married” and both spouses have income, enter the combined salary.) Percentage of gross income contributed to a pension fund Your program must consist of at least the following functions: Function getData: This function asks the user to…arrow_forward
- Write a program that reads the amount of a monthly mortgage payment andthe amount still owed—the outstanding balance—and then displays theamount of the payment that goes to interest and the amount that goes toprincipal (i.e., the amount that goes to reducing the debt). Assume that theannual interest rate is 7.49 percent. Use a named constant for the interest rate.Note that payments are made monthly, so the interest is only one twelfth ofthe annual interest of 7.49 percent.arrow_forwardAn instructor gives a series of exams during the semester in her math class. At the end of the semester she drops each student's lowest test score before averaging the scores. She has asked you to design a program that will read a student's test scores as input and calculate the average with the lowest score dropped. Here is the algorithm that you developed: Get the student's test scores. Calculate the total of the scores. Find the lowest score. Subtract the lowest score from the total. This gives the adjusted total. Divide the adjusted total by 1 less than the number of test scores. This is the adjusted average. Display the average. The test scores are in a text file named scores.txt and contains the following: Mickey, 71.0, 42.0, 83.0 Donald, 94.0, 73.0, 72.0, 81.0 Minnie, 95.0, 85.0, 45.0, 55.0, 65.0 A sample run is as follows: Enter a file containing floating point numbers: scores.txt Test scores for Mickey: ['71.0', '42.0', '83.0'] Removed the lowest score of 42.0 for Mickey The…arrow_forwardA mobile phone service provider has three different subscription packages for its customers: Package A: For $39.99 per month, 450 minutes are provided. Additional minutes are $0.45 per minute. Package B: For $59.99 per month, 900 minutes are provided. Additional minutes are $0.40 per minute. Package C: For $69.99 per month, unlimited minutes are provided. Write a program that calculates a customer’s monthly bill. It should ask the user to enter the letter of the package the customer has purchased (A, B, or C) and the number of minutes that were used. The program should display the total charges.arrow_forward
- Please write a program which prints out the following story. The user gives a name and a year, which should be inserted into the printout. Please type in a name: Mary Please type in a year: 1572 Mary is a valiant knight, born in the year 1572. One morning Mary woke up to an awful racket: a dragon was approaching the village. Only Mary could save the village's residents. The story should change according to the input given by the user.

- Write a program that calculates the potential energy of 3 charges q1 = 1, q2 = 2, q3 = 3 located at points (1,2, 3), (3, –4, –5), and (-4, 2, –6) respectively. The units are coulombs for charge and meters for coordinates. The energy is given by the expression 9293 9193 9142 + T12 U = k r23 T13 where is the distance between the charges q; and q;, and k = 9 × 10º in SI units. Tij Your program should print the result on the screen.arrow_forwardWrite a program that helps a company manage salaries of its employees. Your program should ask for the number of hours worked and the hourly rate of an employee than, display the salary. This program should allow the user to enter the information of many employees until enters -1. Sample Run: Enter the number of hours worked (-1 to end): 32 Enter hourly rate of the worker: 100 Balary is 03200 Enter the number of hours Worked (-1 to end) : 40 Enter hourly rate of the worker: 5 Balary is 3200 Enter the number of hours worked (-1 to end): 42 Enter hourly rate of the worker: 10 Salary is 0420 Enter the number of hours worked (-1 to end) : -1arrow_forwardwrite a java programarrow_forward
