Madelyn made note of all the bicycles and cars she could see parked or locked on a certain city block. All the cars had exactly four wheels, and all the bicycles had exactly two wheels. How many vehicles were on the block if there were 12 bicycles and 4 cars? How many vehicles were on the block if there were x bicycles and y cars?

a) 16 vehicles

b) (x + y) vehicles

Step-by-step explanation:

According to US traffic laws, bicycles are also considered to be vehicles since they are a mode of transport as they can attain speeds far more than humans walking.

Now, if there are 12 bicycles and 4 cars, it means;

Number of vehicles = 12 + 4 = 16 vehicles.

If there are x bicycles and y cars, it means;

Number of vehicles = (x + y) vehicles
