Problem Statement Paste This Into The Top Of Your Submissionbob Runs

Bob runs a food truck business with four trucks. Every day, each truck leaves the warehouse and travels to a different part of town, selling food at multiple construction sites. To better understand his business, he collects metrics every day for each truck. The metrics include 1) the number of sites visited, 2) the cost of gas for the day, and 3) the revenue. Each day in the morning, the first thing Bob wants to do is generate a consolidated report of the previous days’ metrics.

Bob has hired you to develop a program that he can run on a computer, where he can enter those previous day’s metrics and be shown a consolidated output report. To enter metrics into the program, Bob will first enter the date - one time only. After this, he will start entering the data for each individual truck in this order: Truck ID, number of sites visited, gas expense, and revenue. After each item of data has been entered, that data should immediately be shown to Bob on the computer screen to allow him to ensure the data is correct. After all the data for a given truck is entered, the program should display the profit for that truck, calculated as the revenue minus the gas expense.

After Bob has entered ALL the data for ALL the trucks, he should enter the value “End” as a Truck ID to let the program know that there will be no further entries. After Bob has entered “End,” the program should display a summary of the data. The summary must display the overall total number of trucks, total gas expense, total revenue, total profit, and the average profit for the trucks. Additionally, the report must display the highest profit out of all the trucks, and the Truck ID which had that highest profit. In the event of more than one truck earning the highest profit, only the first truck entered into the system should be reported.

Paper For Above instruction

Develop a comprehensive program that facilitates daily data entry and summarized reporting for Bob’s food truck operations. The program must allow the user to input the date once, then proceed to input multiple trucks' operational metrics, displaying individual data and calculated profits after each entry. Upon completion, marked by entering “End” as the Truck ID, the program should provide an overall summary including total trucks, sums of gas expenses, revenue, and profits, as well as the average profit and the highest profit with its corresponding Truck ID. The solution should be implemented using a programming language suitable for user interaction and data processing, ensuring data validation and clear presentation of information.

Solution

To implement the described system, I will develop a Python program that captures the daily metrics for Bob's fleet of trucks, processes the data to compute individual and aggregate metrics, and generates a detailed report. The program's design will prioritize user interaction, clarity, and robustness, ensuring data validity and accurate calculations at every step.

Program Structure and Workflow

The program begins by prompting the user to enter the date of operation. It then enters a data collection loop, where each truck’s data—Truck ID, number of sites visited, gas expense, and revenue—is input sequentially. After each truck's data entry, the program displays the individual details and the calculated profit, ensuring data accuracy and providing immediate feedback. When the user inputs “End” as the Truck ID, the loop terminates, prompting the program to generate and display the summary report.

Data Entry and Validation

Input validation is critical to prevent errors: numeric fields such as sites visited, gas expense, and revenue must be validated to accept only positive numbers. The Truck ID should be handled as a string to accommodate various formats. The program should also handle case sensitivity for the “End” command.

Calculations

For each truck, profit is calculated as:

Profit = Revenue - Gas Expense

The total sums for gas expenses, revenue, and profit are accumulated across all trucks. The average profit is computed by dividing the total profit by the number of trucks, considering only those trucks entered before the “End” command.

The highest profit is tracked dynamically during data entry. If multiple trucks have the same highest profit, only the first encountered is recorded, aligning with the problem requirements.

Output Formatting

The final summary report clearly displays:

  • Total number of trucks
  • Total gas expense
  • Total revenue
  • Total profit
  • Average profit
  • Highest profit and the Truck ID that achieved it

This structured approach ensures comprehensive, accurate, and user-friendly reporting aligned with Bob's operational needs.
