# assign 100 to var cars

# assign 4.0 to var space_in_a_car
space_in_a_car = 4.0
# assign 30 to var drivers
drivers = 30
# assign 90 to var passengers
passengers = 90
# substract drivers from cars and assign it to var cars_not_driven
cars_not_driven = cars - drivers
# assign drivers to var cars_driven
cars_driven = drivers
# assign cars-driven multiplied by space_in_a_car to var carpool_capacity
carpool_capacity = cars_driven * space_in_a_car
# assign passengers divided by cars_driven to var average_passengers_per_car
