The finished goods units on hand on December 31, 2018, was 2,000 units. Each unit requires 2 pounds of raw materials that are estimated to cost an average of $4 per pound. It is the company's policy to maintain a finished goods inventory at the end of each month equal to 20% of next month's anticipated sales. They also have a policy of maintaining a raw materials inventory at the end of each month equal to 30% of the pounds needed for the following month's production. There were 5,760 pounds of raw materials on hand at December 31, 2018.

Driver’s License Exam 20PTS PYTHON AND FLOWCHART The local driver’s license office has asked you to design a program that grades the written portion of the driver’s license exam. The exam has 20 multiple choice questions. Here are the correct answers: 1.B 6.A 11.B 16.C 2.D 7.B 12.C 17.C 3.A 8.A 13.D 18.B 4.A 9.C 14.A 19.D 5.C 10.D 15.D 20.A Your program should store these correct answers in an array. (Store each question’s correct answer in an element of a String array.) The program should ask the user to enter the student’s answers for each of the 20 questions, which should be stored in another array. After the student’s answers have been entered, the program should display a message indicating whether the student passed or failed the exam.(A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly answered questions.

Open Market Operations a) What is an open market operation by a central bank? b) What is the difference between an open market operation and a discount window operation by a central bank? c) Why does a rise in the level of government bond interest rates reduce the amount of private borrowing from commercial banks and vice-versa? d) Suppose that the economy is in a deep recession – unemployment is very high because the level of aggregate demand is very low.

USE C++: Encryption and Decryption are two cryptographic techniques. Encryption is used to transform text to meaningless characters, and decryption is used to transform meaningless characters into meaningful text. The algorithm that does the encryption is called a cipher. A simple encryption algorithm is Caesar cipher, which works as follows: replace each clear text letter with a letter chosen to be n places later in the alphabet. The number of places, n, is called the cipher key. For example, if the cipher key is 3, the clear text“HELLO THERE” becomes “KHOOR WKHUH”.Here, we restrict ourselves to encrypting/decrypting digits (0...9), lowercase, and uppercase alphabetic characters. As you know from the ASCII table, the set of these characters correspond to the integers 48to 122.Hint: The following formula can be used to encrypt a character C using the Caesar cipher algorithm: E = (C –‘0’ + k) % 75+ ‘0’ [where k is the cipher key]You need to figure out the formula for decrypting text on your own.NOTE: Use cipher key = 7.Write a C++ program for encrypting and decrypting a given string. Since this program performs two different functionalities (encryption and decryption), prompt the user to select the type of cryptographic technique as shown below: Welcome to Cryptographic Techniques ProgramPlease enter your selection:1. Encrypt2. DecryptWhen the user selects 1 or 2, s/he will be asked to specify an input and output message. Here is an example: Assume that the user enters the following message: HOW ARE YOU DOING? If the user selects to encrypt the message (i.e. option 1), the program will encrypt the original message and outputs an encrypted text. If the user selects to decrypt a message (i.e. option 2), the program will decrypt the encrypted text and outputs the decrypted text on the screen. The program should give the user the option of whether to continue with encrypting/decrypting messages (i.e. entering the letter ‘C’) or exit the program (i.e. entering the letter‘E’).
