Let's break down the problem and solution **step by step**, as you requested: --- ### **Step 1: Introduction to the Concept** The problem is about **calculating the cost of driving** a car for different trip distances (20, 75, and 500 miles), given the car's mileage (miles per gallon) and the price of gas per gallon. You need to write a program that accepts mileage and gas price as input, then calculates and outputs the cost for each distance. --- ### **Step 2: Input Collection** You need to **input**: - The car's mileage (miles per gallon) - The cost of gas (dollars per gallon) These values are typically taken as user input. --- ### **Step 3: Calculating Costs** For each distance (20, 75, and 500 miles), you: - Calculate the **number of gallons needed**: `distance / mileage` - Calculate the **cost for that distance**: `(distance / mileage) * gas_price` You repeat this for each of the three distances. --- ### **Step 4: Output Format** Print the three calculated costs on a single line, separated by spaces. --- ### **Step 5: Sample Calculation** If input is: - Mileage: 25.0 miles/gallon - Gas price: $3.159/gallon Then for 20, 75, and 500 miles: - 20 miles: `(20 / 25.0) * 3.159 = 2.53` - 75 miles: `(75 / 25.0) * 3.159 = 9.48` - 500 miles: `(500 / 25.0) * 3.159 = 63.18` Output: `2.53 9.48 63.18` --- ### **Step 6: Final Python Code** ```python # Step 1: Input values mileage = float(input()) gas_price = float(input()) # Step 2: Calculate costs for each distance for distance in [20, 75, 500]: cost = (distance / mileage) * gas_price print(f"{cost:.2f}", end=' ') ``` --- ### **Final Answer in Few Sentences** The program reads the car's mileage and gas price, calculates the cost for trips of 20, 75, and 500 miles, and prints those costs rounded to two decimals on one line. --- ### **Summary of the Steps** 1. **Introduction:** Explained the goal (calculating trip costs based on mileage and gas price). 2. **Input:** Described taking mileage and gas price as input. 3. **Calculation:** Showed the formula for calculating trip cost. 4. **Output:** Described printing the results. 5. **Sample:** Provided a sample calculation. 6. **Code:** Presented the complete Python code. 7. **Final Answer:** Summarized the task and approach.
