Question

For the following program descriptions, write step by step pseudo code that shows you understand the problem and what it takes to solve it. The first one is done for you as an
example. Please answer the questions in the same format as the example problem below so it is the same.

Example #1 Problem
A customer is purchasing five items. Design a program where you collect the amount of each item,
calculate the subTotal of the items, the tax at 7%, and a grand total. The output will display the subTotal,
tax and grand total formatted with 2 decimal places and a $.

Answer
Declare variables: item1, item2, item2, item4, item5, subtotal, tax, grandTotal
Declare constant TAX_RATE=0.07
Get the price for each item
Calculate the subtotal=item1 + item2 + item3 + item4 + item5
Calculate the tax = subtotal * TAX_RATE
Calculate the grandTotal=subtotal + tax
Display the subtotal
Display the sales tax
Display the grandTotal

Question

3. Design a program that calculates the total amount of a meal purchased at a restaurant. The program
should ask the user to enter the charge for the food, then calculate the amount of an 18% tip and 7%
sales tax and the total cost of the meal including the tax and tip.
4. Design a program that asks the user for the number of males and females registered in a class. The
program should display the percentage of males and females in the class. You will need to calculate the
total number of students first to get the percentage of males and females.

Answer 1

Solution:

The pseudocode for the given problem is given below:

Declare variables: meal_amount, grandTotal

Declare constant = TIP_AMOUNT = 0.18, SALES_TAX = 0.07

Get the amount of meal purchased

Calculate the Sales_tax_amount = meal_amount * SALES_TAX

Calculate the Tip_amount = meal_amount * TIP_AMOUNT

Calculate the grandTotal = meal_amount + Tip_amount + Sales_tax_amount

Display the grandTotal

Explanation:

• First declare the variables to store the meal amount and the total amount after all the computations.
• Define the constant variables to be used.
• Prompt the user to enter the amount of meal.
• Compute the amount after applying the sales tax.
• Compute the amount after applying the tip percentage on meal amount.
• Compute the grand total which is the summation of the entered meal amount and the percentage amount of sales and tip applied to it.
• Display the grand total amount.

4.

Solution:

The pseudocode for the given problem is given below:

Declare variables: num_males, num_females

Get the number of male and female number of students.

Calculate total_students = num_males + num_females

Calculate the Male_percentage = (num_males/total_students) * 100

Calculate the female_percentage = (num_females/total_students) * 100

Display the Male_percentage

Display the female_percentage

Explanation:

• Declare the variable that takes the number of male and female count.
• Compute the total number of students which is the summation of number of males and females count.
• Compute the percentage of male.
• Compute the percentage of female.
• Display the percentage of male student in the class.
• Display the percentage of female student in the class.
