Answer: Detailed

Explanation:

SDLC consist of 7 phases. They are:

1. Planning.

2. System analysis and requirement

3. Design:

4. Coding:

5. Testing:

6. Installation

7. Maintenance

Here we are talking of the third phase. In this phase it is the design phase which consist of high and low level design. Here the preliminary design is included in high level design where it describes the required hardware, software, network capabilities and the modelling of the interface. However the detailed design in low level design will implement the coding and will finding of any errors in the implemented design as described by the preliminary design.

In cell F29, use an IF function to display the correct Shipping Charge, based on the amount of the Discounted Total. If the Disc
sladkih [1.3K]

Answer:

= IF(B29 >= B28,0,(0.05 * B29))

Explanation:

Given

Free Shipping Minimum = B28

Shipping Charge = F29

Required

Write a formula in F29 to calculate the total shipping charge based on the condition in the question.

To solve this, the following assumption needs to be made.

It'll be assumed that cell B29 contains the value for Discounted Total.

So,

Discounted Total = B29

The condition in the question says

1. If Discounted Total (B29) is greater than or equal to the Free Shipping Minimum (B29), then Shipping Charge (F29) is 0

This can be represented as

If(B29 >= B28)

F29 = 0

2. Else (i.e. if (1) above is false), Shipping Charge (F29) equals 5% of Discounted Total (B29)

This can also be represented as

F29 = 0.05 * B29

Writing the formula in (1) and (2) together in Excel format;

= IF(B29 >= B28, 0, (0.05 * B29))

The above formula will give the desired result based on the condition in the question.

Take for instance;

Free Shipping Minimum = B28 = 28

Discounted Total = B29 = 30

Since 30 >= 28, the value of F29 will be 0 because it satisfies condition 1.

But if

Free Shipping Minimum = B28 = 30

Discounted Total = B29 = 28

Since 28 < 30, the value of F29 will be 5% of 28 = 1.4 because it satisfies condition 2

Create a dictionary that will hold AT LEAST 3 categories for food with at least 3 foods for each category. E.g. Fruits --&gt; Ap
RSB [31]

Answer:

  1. food_category = {
  2.    "Fruits": ["Apple", "Strawberries", "Orange"],
  3.    "Vegetables": ["Carrots", "Peas", "Onions"],
  4.    "Meats": ["Chicken", "Beef", "Mutton"]
  5. }
  6. for cat in food_category:
  7.    output = cat + ": "
  8.    for food in food_category[cat]:
  9.        output += food + ", "
  10.    print(output)
  11. answer = input("Do you want to add category or food (Y - Yes  N - No): ")
  12. while(answer == "Y"):
  13.    choice = input("New Category (N) or New Food (nf): ")
  14.    
  15.    if(choice == "N"):
  16.        new_cat = input("Enter new category name: ")
  17.        if(new_cat not in food_category):
  18.            food_category[new_cat] = ""
  19.    elif(choice == "nf"):
  20.        cat = input("Enter category: ")
  21.        new_food = input("Enter new food name: ")  
  22.        food_category[cat].append(new_food)
  23.    
  24.    answer = input("Do you want to add new category or food (Y - Yes N - No): ")
  25. print("All food categories: ")
  26. for cat in food_category:
  27.    print(cat)
  28. selected_cat = input("Select a category to view the food list: ")
  29. output = ""
  30. for food in food_category[selected_cat]:
  31.    output += food + ", "
  32. print(output)

Explanation:

The solution code is written in Python 3.

Firstly, create a food category dictionary data structure (Line 1 -5). Next, display all the food category and the food in each category (Line 7 - 11)

Next prompt user to feedback if they wish to add new category or new food (Line 13).

While the answer is yes prompt user to enter their choice, either category or food and use if else if statements to handle the choice made by the user. If the choice is new category, prompt user to enter new category name and check if the new category is already exist in the dictionary. If not, add that category to dictionary (Line 18 - 21).

If the choice is food, nf, prompt user to input food category and enter the new food name and add it to the food_category list (Line 22 - 25).

After that prompt user to enter if they wish to continue to add new data (Line 27).

After collecting all info from user, write a for loop to display all the categories (Line 29 - 31).

At last, prompt user to select a category and display all the food of the selected category (Line 33 - 37).
