I am having issues on trying to get the profit this is the question- In the ChiliToGo program in Exercise 12, the costs to produce an adult meal and a child’s meal are $4.35 and $3.10, respectively. Adult meals are sold for $7 and children's meals are sold for $4. Modify the ChiliToGo program to display the total profit for each type of meal as well as the grand total profit. This is what code it starts with-  import java.util.Scanner; class ChiliToGoProfit {   public static void main(String[] args) {       // Modify the code below       final double ADULT_PRICE = 7;       final double CHILD_PRICE = 4;       int adultMeals;       int childMeals;       double totalAdult, totalChild, grandTotal;       Scanner input = new Scanner(System.in);       System.out.print("Enter number of adult meals ordered >> ");       adultMeals = input.nextInt();       System.out.print("Enter number of child meals ordered >> ");       childMeals = input.nextInt();       totalAdult = adultMeals * ADULT_PRICE;       totalChild = childMeals * CHILD_PRICE;       grandTotal = totalAdult + totalChild;       System.out.println(adultMeals + " adult meals were ordered at " + ADULT_PRICE + " each.");       System.out.println("      Total is " + totalAdult);       System.out.println(childMeals + " child meals were ordered at " + CHILD_PRICE + " each.");       System.out.println("      Total is " + totalChild);       System.out.println("Grand total for all meals is " + grandTotal);    } }

Question

I am having issues on trying to get the profit this is the question- In the ChiliToGo program in Exercise 12, the costs to produce an adult meal and a child’s meal are $4.35 and $3.10, respectively. Adult meals are sold for $7 and children's meals are sold for $4. Modify the ChiliToGo program to display the total profit for each type of meal as well as the grand total profit.

This is what code it starts with- 

import java.util.Scanner;
class ChiliToGoProfit
{
  public static void main(String[] args) {
      // Modify the code below
      final double ADULT_PRICE = 7;
      final double CHILD_PRICE = 4;
      int adultMeals;
      int childMeals;
      double totalAdult, totalChild, grandTotal;
      Scanner input = new Scanner(System.in);
      System.out.print("Enter number of adult meals ordered >> ");
      adultMeals = input.nextInt();
      System.out.print("Enter number of child meals ordered >> ");
      childMeals = input.nextInt();
      totalAdult = adultMeals * ADULT_PRICE;
      totalChild = childMeals * CHILD_PRICE;
      grandTotal = totalAdult + totalChild;
      System.out.println(adultMeals + " adult meals were ordered at " + ADULT_PRICE + " each.");
      System.out.println("      Total is " + totalAdult);
      System.out.println(childMeals + " child meals were ordered at " + CHILD_PRICE + " each.");
      System.out.println("      Total is " + totalChild);
      System.out.println("Grand total for all meals is " + grandTotal);
   }
