A store provides 10 percent discount on all items with a price of at least $100. No discount is otherwise applicable. Which of the following DOES NOT correctly compute the discount? explain your choice. a) double discount = 0; if (price >= 100) { discount = 0.10 * price; } b) double discount = 0.10 * price; if (price <= 100) { discount = 0; } %3!

uppose you have a certain amount of money in a savings account that earns compoundmonthly interest, and you want to calculate the amount that you will have after a specificnumber of months. The formula, which is known as the future value formula, is:F=P×(1+i)tThe terms in the formula are as follows:o F is the future value of the account after the specified time period.o P is the present value of the account.o i is the monthly interest rate.o t is the number of months.Write a program that prompts the user to enter the account’s present value, monthlyinterest rate, and the number of months that the money will be left in the account. Theprogram should pass these values to a function named futureValue that returns thefuture value of the account, after the specified number of months. The program shoulddisplay the account’s future value. i attached the screenshot of the output so the output should look like that. the coding should be in c++
If num_cards is: 36, output 'Short deck'. • 48, output 'Pinochle'. 52, output 'Standard'. Otherwise, output 'Other deck size'.

Visual Basic For tax purposes an item may be depreciated over a period of several years, n.With the straight line method of depreciation, each year the item depreciates by 1/nth of itsoriginal value. With the double declining balance method of depreciation, each year the itemdepreciates by 2/nths of its value at the beginning of that year. (In the final year it is depreciatedby its value at the beginning of the year.)Write a program using Visual Basic that performs the following tasks:1.1 Request a depreciation of the item, the year of purchase, the cost of the item, the number ofyears to be depreciated (estimated life), and the method of depreciation. The method ofdepreciation should be chosen by clicking on one of two buttons.1.2 Display a year by year description of the depreciation.
In the Dice Roll game, the player begins with a score of 1000. The player is prompted for the numberof points to risk and a second prompt asks the player to choose either high or low. The player rollstwo dice and the outcome is compared to the player’s choice of high or low. If the dice total is between2 and 6 inclusive, then it is considered “low”. A total between 8 and 12 inclusive is “high”. A total of7 is neither high nor low, and the player loses the points at risk. If the player had called correctly, thepoints at risk are doubled and added to the total points. For a wrong call, the player loses the points atrisk. Create a DiceRollGame application that uses a DRPlayer object based on this specification. TheDRPlayer object should have two Die member variables that represent the dice. The Die class shoulduse a random number generator to determine the outcome in a roll() method. Application outputshould look similar to:
Int a=2 b=3 What is the result of the following conditions? a<=b a==b !(a==b) (a<=b) && (a==b) (a<=b) || (a==b)

Simplex Method Exercise A toy store uses three operations to assemble three types of toys: trains, trucks, and cars. The daily times available for the three operations are 430, 460, and 420 minutes, respectively, and the revenue per train unit, toy truck and car are $3, $2, $5 USD. The assembly times per train in the three operations are 1, 3 and 1 minutes. The corresponding times per truck 2, 0 and 4 minutes. As for cars, they are 1, 2 and 0 minutes (a time zero indicates that the operation is not used. Let x, y, and z The daily quantities of assembled units of trains, trucks and cars, respectively, are all summarized in the following table: Variables Case: Toy store - Simplex Method The decision variables are the items that are going to be produced in this case trains, trucks and cars. x1 = trains x2 = trucks X3 = cars Objective Function The objective function of the problem is determined by income Z = INCOME MAX Z = 3X1 + 2X2 + 5X3 Restrictions Case: Toy store - Simplex Method…
