Question

I'm getting an error on the output. How do I get it to print:

The gas cost for 10 miles is $1.58

The gas cost for 50 miles is $7.90

The gas cost for 400 miles is $63.20

### Programming Exercise: Calculating Gas Costs #### Objectives: - Create a function to match the specifications. - Use floating-point value division. - Acquire user input, call the custom function, and produce the desired output using a `format` function for specified precision. #### Instructions: Driving is expensive. Write a program using a car's miles/gallon and gas dollars/gallon (both floats) as input to calculate and output the gas cost for driving 10 miles, 50 miles, and 400 miles. Ensure that each floating-point value is displayed with two digits after the decimal point. This can be achieved using the following code: ```python print('{:.2f}'.format(your_value)) ``` **Example Input:** ``` 20.0 3.1599 ``` **Expected Output:** ``` The gas cost for 10 miles is $1.58 The gas cost for 50 miles is $7.90 The gas cost for 400 miles is $63.20 ``` Your program should define and call the `driving_cost()` function. This function takes three input parameters: `driven_miles`, `miles_per_gallon`, and `dollars_per_gallon`. It calculates and returns the dollar cost for driving the specified miles. **Example Function Call:** Implement the function with the correct logic to fulfill the above requirements.

It calculates and returns the dollar cost for driving the specified miles. **Example Function Call:** Implement the function with the correct logic to fulfill the above requirements.
### Driving Costs - Functions #### Function Execution Example: ```plaintext 50 20.0 3.1599 ``` The function returns: ```plaintext 7.89975 ``` #### Function Definition: ```python def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) ``` Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles. **Hint:** To calculate how many gallons I will spend to drive 1 mile I will divide 1 by a car’s miles/gallon parameter. **Note:** Pay attention to the distinction of what the function expects and is supposed to do versus what the program needs to collect and do. In this lab, the function has 3 parameters, whereas the program collects only 2 input values because the miles are already pre-determined (i.e., hard-coded) inside of its code. --- #### Main Activity Code: ```python # Define your function here. def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon): return (driven_miles/miles_per_gallon)*dollars_per_gallon if __name__ == '__main__': # Type your code here. miles_per_gallon = float(input()) dollars_per_gallon = float(input()) print('{:.2f}'.format(driving_cost(10, miles_per_gallon, dollars_per_gallon))) print('{:.2f}'.format(driving_cost(50, miles_per_gallon, dollars_per_gallon))) print('{:.2f}'.format(driving_cost(400, miles_per_gallon, dollars_per_gallon))) ``` This code snippet is part of a lab activity designed to teach students how to work with functions in Python. The main task is to calculate the cost of driving different distances based on input values for miles per gallon and dollars per gallon.
