Design an algorithm to assist a school to calculate it's canteen which sum up to 12cedis displaying your answer in a constant P by step 1START To step 7 STOP

1 answer

To create an algorithm that assists a school in calculating its canteen expenses summing up to 12 cedis, we'll outline a clear step-by-step process. The final output will involve displaying the result in a constant variable, let's name that constant P. Below is a structured algorithm that works in seven simple steps.

Algorithm

  1. START
    Begin the algorithm.

  2. Initialize Variables
    Set a constant variable P = 12.
    Additionally, you may want to initialize a variable sum = 0 to hold the accumulated expenses.

  3. Input Item Prices
    Prompt the user to enter the prices of items sold in the canteen until the total reaches or exceeds 12 cedis.
    Use a loop to continue prompting for prices.

  4. Update Sum
    For each entered price, add it to sum.
    If sum exceeds 12, alert the user that they have exceeded the budget.

  5. Check Total
    If sum equals 12, confirm to the user that they have met the target of 12 cedis.
    If sum is less than 12, inform the user how much more they need to reach 12 cedis.

  6. Display Result
    Set P = sum if sum equals 12, and prepare to display the result.
    Display the message: “Total Canteen Expenses: P cedis”.

  7. STOP
    End the algorithm.

Pseudocode

1. START
2. P = 12
3. sum = 0
4. WHILE sum < P DO
    a. PROMPT "Enter the price of the item:"
    b. INPUT price
    c. sum = sum + price
    d. IF sum > P THEN
        i. DISPLAY "Exceeded the budget!"
    e. ENDIF
ENDWHILE
5. IF sum == P THEN
    a. DISPLAY "You have met the target of 12 cedis."
ELSE
    a. DISPLAY "You need " + (P - sum) + " more cedis to reach 12 cedis."
ENDIF
6. DISPLAY "Total Canteen Expenses: " + sum + " cedis."
7. STOP

Explanation

  • Start: The algorithm initiates at step 1.
  • Initialization: A constant P is used to define the target sum (12 cedis).
  • Input Loop: The algorithm continues to accept item prices until the total reaches or exceeds 12 cedis.
  • Updating the Sum: Each time a price is entered, it's added to the sum. If the total exceeds 12, a warning is issued.
  • Check and Display: The final decision checks if the sum is equal to or less than 12 and displays the appropriate messages.
  • End: The process concludes gracefully.

This algorithm can be implemented in any programming language to facilitate the canteen calculations effectively.
