Question
Use Raptor to answer the following questions
The manager of the Super Supermarket would like to be able to compute
the unit price for products sold there. To do this, the program should input
the name and price of an item per pound and its weight in pounds and
ounces. Then it should determine and display the unit price (the price per
ounce) of that item and the total cost of the amount purchased. You will
need the following variables:
ItemName Pounds Ounces
PoundPrice TotalPrice UnitPrice
You will need the following formulas:
UnitPrice = PoundPrice/16
TotalPrice = PoundPrice * (Pounds + Ounces/16)

- Summary 2 HouseSign.py - This program calculates prices for cu house signs. In this lab, you complete a prewritten Python program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based 4 on the following facts: 5 # Declare and initialize variables here. 6 # Charge for this sign. • The charge for all signs is a minimum of $35.00. # Number of characters. 8 # Color of characters. • The first five letters or numbers are included in the minimum charge; there is a $4 charge for 9 # Type of wood. 10 each additional character. 11 # Write assignment and if statements here as appropr • If the sign is make of oak, add $20.00. No charge is added for pine. 12 13 # Output Charge for this sign. • Black or white characters are included in the minimum charge; there is an additional $15 14 print("The charge for this sign is $" + str(charge)) charge for gold-leaf lettering. 15 Instructions 1.

- A retail company assigns a $5000 store bonus if monthly sales are more than $100,000; otherwise a $500 store bonus is awarded. Additionally, they are doing away with the previous day off program and now using a percent of sales increase to determine if employees get individual bonuses. If sales increased by at least 4% then all employees get a $50 bonus. If they do not, then individual bonuses are 0. Step 7: The final step in completing the pseudocode is to call all the modules with the proper arguments. Complete the missing lines. Module main () //Declare local variables Declare Real monthlySales Declare Real storeAmount Declare Real empAmount Declare Real salesIncrease //Function calls Call getSales(monthlySales) Call getIncrease(salesIncrease) Call ______________(_______________, _____________) Call ______________(_______________, _____________) Call ______________(_______________, _____________) End Modulearrow_forwardAssume that the population of Mexico is 128 million and the population of the United States is 323 million. Write a program called Population that accepts two values from a user: an assumption of an annual increase in the population of Mexico and an assumption for an annual decrease in the U.S. population. Accept both figures as percentages; in other words, a 1.5 percent decrease is entered as 0.015. Write an application that displays the populations of the two countries every year until the population of Mexico exceeds that of the United States, and display the number of years it took. An example of the program is shown below: Enter the percent annual increase for Mexico population Enter as a decimal. For example, 0.5% is entered as 0.005 Enter the value >> 0.008 Enter the percent annual decrease for U.S. population Enter as a decimal. For example, 0.5% is entered as 0.005 Enter the value >> 0.002 Mexico population U.S. Population 1 129.024 million 322.354 million 2…arrow_forwardA retail company assigns a $5000 store bonus if monthly sales are $100,000 or more. Additionally, if their sales exceed 125% or more of their monthly goal of $90,000, then all employees will receive a message stating that they will get a day off. Step 3: Complete the pseudocode by writing the missing lines. When writing your modules and making calls, be sure to pass necessary variables as arguments and accept them as reference parameters if they need to be modified in the module. (Reference: Writing a Decision Structure in Pseudocode, page 118).
