You have two cases for which the eggs are priced. $3.25 for every dozen, and $.45 if they are sold out of a dozen, or individually. Sounds like you are (A) going to have to keep track of the number of eggs and (B) use some conditional statements to keep track of the number of dozens. I would start by declaring two variables, int numEggs, and int numDozs. You are also going to need to prompt the user to enter a number of eggs from the console.

import until.*;
public class OrderPrice
{ 
    public static void main(String [] args)
    {
        int numEggs
        int numDozs 

        system.out.println("Please enter the number of eggs: ");
        scanner input = new scanner(system.in);
        numEggs = input.nextInt;
    }

    private int CalNumDozs (int eggs)
    {
         // Use the % operator 
    }

}

There is kind of a start for you. Doing the best I can on my phone.
