- Malcolm Movers charges a base rate of $200 per move plus $150 per hour and $2 per mile. Write a program named MoveEstimator that prompts a user for and accepts estimates for the number of hours for a job and the number of miles involved in the move and displays the total moving fee.arrow_forwardSoftware SalesA software company sells a package that retails for $99. Quantity discounts are given accordingto the following table:Quantity Discount10–19 10%20–49 20%50–99 30%100 or more 40%Write a program that asks the user to enter the number of packages purchased. The programshould then display he number of packages purchased, the amount of the discount (if any) and the total amount of the purchase after the discount.arrow_forwardXYZ Company, LLC uses a program to manage the information of their employees. The program gets the name of the employee, number of hours worked and rate per hour. It computes the salary by multiplying the number of hours worked with rate per hour. If the salary is more than 1000, tax is computed as 5% of the salary, otherwise, tax is computed as 2% of the salary. The program will display the name of the employee, salary and tax.arrow_forward
- The BlueMont chain hotels have 4 different types of room: Single room: $60/night Double room: $75/night King room: $100/night Suite room: $150/night The size of the hotel chains in different locations may be different in terms of the number of floors and the type and the number of rooms on each floor. You are required to write a program that calculates the occupancy rate and the total hotel income for one night and displays this information as well as some other information described below. The program starts by asking the location where this hotel chain is located and the number of floors in the hotel. The number of floors may not exceed 5. The User then enters the total number of rooms for each floor. The program then asks specifically the number of occupied rooms for each room type on this floor. The total number of rooms on each floor may not exceed 30 and the program should check that the total number of occupied rooms on each floor does not exceed the total of rooms on…arrow_forwardThe company discounted used cars pays their employees according to this chart: 250$ per months plus 50$ per car sold. If the salesman sells more than 10 cars, the employee receives a bonus of 5% of the total of his sales, in addition to his regular salary.Each month, the owner sits in front of the computer, and enters the following information: The name of the employee, the number of cars sold, as well as the total of all the sales for the month. algorithm that will calculate the salary of an employee for the month, and then display on the screen, his name, total cars sold, base salary, bonus if applicable and entire salaryarrow_forwardDuring each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly.

You are ordering food from a restaurant that has two menu items: Tacos $4 Empanadas $3 Calculate and print out all the options of meals where the budget is used entirely(where possible) and each person has an equal number of items to eat. They may eat different things, but everyone gets the same number of food items, e.g. 2 tacos or 1 empanada and 1 taco or 2 empanadas. Hints: Here are some things that might help you in your solution. If total items purchased does not equally divide by the number of diners, then abandon that combination. It may help to calculate the max number of empanadas that the budget can buy and also the max number of tacos that the budget could buy. These can be thought of as upper bounds in your loops. In your solution, keep track of items per person Also, keep track of total number of viable solutions, as that might…arrow_forwardQuestion: Party budget planning - complex Prompt the user to enter their current budget and the number of people who need to share a meal.

- The monthly payment for a given loan pays the principal and the interest. The monthly interest is computed by multiplying the monthly interest rate and the balance (the remaining principal). The principal paid for the month is therefore the monthly payment minus the monthly interest. Write a program that lets the user enter the loan amount, number of years, and interest rate and displays the amortization schedule for the loan in visual basicarrow_forwardoe’s Pizza Palace needs a program to calculate the number of slices a pizza of any size can be divided into. The program should perform the following steps: Ask the user for the diameter of the pizza in inches. Calculate the number of slices that may be taken from a pizza of that size. Display a message telling the number of slices. To calculate the number of slices that may be taken from the pizza, you must know the following facts: Each slice should have an area of 14.125 inches To calculate the number of slices, simply divide the area of the pizza by 14.125. The area of the pizza is calculated with this formula: Area NOTE: π is 3.14159. The variable r is the radius of the pizza. Divide the diameter by 2 to get the radius.arrow_forwardA dramatic theater has three seating sections, and it charges the following prices for tickets in each section: section A seats cost $20 each, section B seats cost $15 each, and section C seats cost $10 each. The theater has 300 seats in section A, 500 seats in section B, and 200 seats in section C. Design a program that asks for the number of tickets sold in each section and then displays the amount of income generated from ticket sales. The program should validate the numbers that are entered for each section. please do flowchart in c++arrow_forward
