Driving costs - functions

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon
(both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles.

Output each floating-point value with two digits after the decimal point, which
can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:

20.0
3.1599
the output is:

1.58
7.90
63.20

Your program must define and call the following driving_cost() function.
Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon,
the function returns the dollar cost to drive those miles.

Use the following .py file to get started:

#variables

miles_per_gallon = float(input("Please enter the miles per gallon: "))
dollars_per_gallon = float(input("PLease enter the cost per gallon: "))

#calculations

dollars_20_miles = 20 * (1.0 / miles_per_gallon) * dollars_per_gallon
dollars_75_miles = 75 * (1.0 / miles_per_gallon) * dollars_per_gallon
dollars_500_miles = 500 * (1.0 / miles_per_gallon) * dollars_per_gallon

#print

print('{:.2f} {:.2f} {:.2f}'.format(dollars_20_miles, dollars_75_miles. dollars_500_miles))

CODE IN PYTHON:

Your task is to write a simple program that would allow a user to compute the cost of a road trip with a car. User will enter the total distance to be traveled in miles along with the miles per gallon (MPG) information of the car he drives and the per gallon cost of gas. Using these 3 pieces of information you can compute the gas cost of the trip.

User will also enter the number of days it will take to complete the trip. For each night (day-1 nights), user will need a hotel. We will ask for the number of stars for the hotel the user wants to stay. 5 star hotel costs $250 per night. 4 star hotel costs $180 per night. 3 star hotel costs $120 per night, 2 star hotel costs $100 per night and finally 1 star hotel costs $50 per night. Using the hotel costs and the number of nights users will need to stay at a hotel, you can compute the hotel cost of the trip.

Please note that 5 star and 4 star hotels give 10% discount if the user will be staying more than 2 nights -- (these are chain hotels, so even if you are staying at different locations discount apply).

We should also account for the cost of meals. This depends on the type of hotel the user is staying. In general, we take 20% of hotel cost as the meal cost (after 10% hotel discount if applicable).

Example Run #1

Distance: 350

MPG : 15

Gas Price: 3.79

Days Traveling : 3

Hotel Stars (1-5) : 3

Your total cost is $376.43333333333334

Example Run #2

Distance: 400

MPG : 20

Gas Price: 2.99

Days Traveling: 1

Hotel Stars (1-5): 5

Your total cost is $59.800000000000004.

Example Run #3

Distance: 150 MPG : 25 Gas Price: 1.99 Days Traveling : 2 Hotel Stars (1-5): 5 Your total cost is $311.94.

Construct a histogram of your empirical data using eight bars and then five bars. For consistency's sake, for eight bars use the class width of 0.125. So, your first bar will be 0.000-0.124, your next bar will be 0.125 - 0.249, etc. For five bars, use the class width of 0.2. So, your first bar will be 0.00-0.19, your next bar will be 0.2-0.39, etc. Upload both pictures of your histograms. ***Below are my 50 random numbers. What do I need to show? I am confused on what exactly I need to show. Can you help me on these?
