# 1. I used 4.0 for space_in_a_car, but is that necessary? What happens if it's just 4? Nothing changes in this case.
# 2. Remember that 4.0 is a floating point number. It's just a number with a decimal point, and you need 4.0 instead of just 4 so that it is floating point.
# 3. Write comments above each of the variable assignments.
# 4-6 completed as well.
