A bag of cookies holds 40 cookies. The calorie information on the bag claims that there are

calories consumed. - CORRECT ANSWER✅✅package javacookies;




import java.util.Scanner;

public class JavaCookies {



public static void main(String[] args) {



int cookieCount;

Scanner keyboard = new Scanner(System.in);

System.out.println("Enter number of cookies eaten:");

cookieCount = keyboard.nextInt();



int servingSize = 40/10;

double caloriesPerCookie = 300/servingSize;

double totalCalories = cookieCount * caloriesPerCookie;



System.out.println("Your calorie intake was: " + totalCalories

+ " calories");



}
