Answer 1

CODE IN JAVA:

MealCost.java file:

import java.util.Scanner;
public class MealsCost {

   public static void main(String[] args) {
       // creating object to the Scanner class to take input from the user
       Scanner sc = new Scanner(System.in);
       // asking number of adult meals sold
       System.out.print("Enter the number of adult meals sold : ");
       int adultMeals = sc.nextInt();
       //asking number of child meals sold
       System.out.print("Enter the number of child meals sold : ");
       int childMeals = sc.nextInt();
       // defining meals cost
       double adultMealCost = 10.0 ;
       double childMealCost = 5.0;
       //calculating total cost
       double totalAdultMealCost = adultMeals * adultMealCost ;
       double totalChildMealCost = childMeals * childMealCost ;
       double totalCost = totalAdultMealCost + totalChildMealCost ;
       System.out.println("Adult dinners : $" + totalAdultMealCost);
       //displaying the result
       System.out.println("Children's dinners : $" + totalChildMealCost);
       System.out.println("Total Meals : $" + totalCost);

   }

}

OUTPUT:
