Please help me with the task: Write using lower camel case.

Hello, I’m working on this task:

Create five int variables. Name them with a lower camel case representation of these strings:
Number of cars
Money amount
Plane speed
Hole depth

int numberOfCars;

Here is my code:

public static class WriteUsingLowerCamelCase
   public static void Main()
       int numberOfCars;
       int moneyAmount;
       int planeSpeed;
       int holeDepth;
       int Age;

Can anyone please help me to solve it?
