Vehicle Tolls

With inheritance, a subclass reuses its parent's behaviour and adds its own. Every vehicle pays a toll; a truck is a vehicle that pays extra for its axles.

Each vehicle is one of:

• motorbike: pays 2.
• car: pays 5.
• truck <axles>: pays the car rate 5, plus 3 for every axle beyond the first two.

Implement vehicle_tolls(vehicles).

Input

vehicles: The vehicles passing the toll gate.

Output

Return the total toll collected.
