Question: Party budget planning - complex
Prompt the user to enter their current budget and the number of people who need to share a meal.
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…

Modify the program you wrote in Programming Challenge 19 so that it reports the number of pizzas you need to buy for a party if each person attending is expected to eat an average of 4 slices. The program should ask the user for the number of people who will be at the party and for the diameter of the pizzas to be ordered. It should then calculate and display the number of pizzas to purchase. Because it is impossible to buy a part of a pizza, the number of required pizzas should be displayed as a whole number.

- Assignment Write a program that tracks how much steps the user walks in total in a day and reports if the daily target is reached or not. The program will keep reading double values, each representing steps walked during an individual activity within a day (stepsWalked) until either the user enters a negative value or the daily target of 5000 steps is met. If the user enters a negative number, the program should print total steps walked as a double. Otherwise, if the target is exactly reached, the program should simply print "Target is reached", finally if the target is surpassed the program should print the text "Target is surpassed by", followed by the excess amount above the target as a double, and finally printing the text "steps". NOTE: You MUST use a repetitive statement in this question. NOTE: Each stepsWalked value will be given as a non-negative value. You do NOT need to check this.

If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food: Calories from fat = Fat grams × 9 If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat: Percentage of calories from fat = Calories from fat ÷ Total calories Create an application that allows the user to enter: • The total number of calories for a food item • The number of fat grams in that food item The application should calculate and display: • The number of calories from fat • The percentage of calories that come from fat Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.) Use the following test data…arrow_forwardPrompt Problem: A company wants a program that will calculate the weekly paycheck for an employee based on how many hours they worked. For this company, an employee earns $20 an hour for the first 40 hours that they work. The employee earns overtime, $30 an hour, for each hour they work above 40 hours. Example: If an employee works 60 hours in a week, they would earn $20/hr for the first 40 hours. Then they would earn $30/hr for the 20 hours they worked overtime. Therefore, they earned: ($20/hr 40hrs)+($30/hr 20 hrs) $800+ $600 = $1400 total. For this assignment, you must create pseudocode and a flowchart to design a program that will calculate an employee's weekly paycheck. - Write pseudocode to design a programming solution by outlining a series of steps and using appropriate indentation and keywords. As you write your pseudocode, be sure to consider the following: What input does the computer need? What steps does the program need to follow to process the input? What output should…arrow_forward

- Retail price calculator Write a program that asks the user to enter an item’s wholesale cost and its markup percentage. It should then display the item’s retail price. For example: • If an item’s wholesale cost is 5.00 and its markup percentage is 100 percent, then the item’s retail price is 10.00.• If an item’s wholesale cost is 5.00 and its markup percentage is 50 percent, then the item’s retail price is 7.50.
