Question

Hello:

Need help with this program. In JavaScript please

// Assume hot dogs come in packages of 10, and hot dog buns come in packages of 8.

// Write a program that calculates the number of packages of hot dogs and the

// number of packages of hot dog buns needed for a cookout, with the minimum amount

// of leftovers. The program should ask the user for the number of people attending

// the cookout. Assume each person will eat 1 hotdog.

//

// The program should display the following details:

//

// The minimum number of packages of hot dogs required

// The minimum number of packages of hot dog buns required

// The number of hot dogs that will be left over

// The number of hot dog buns that will be left over

//

// Hint: You might want to use the % operator in one of your calculation

//

function packagesNeeded(numberOfPeople, itemsPerPack) {

This code does not work:

var minPackageHotDog = Math.ceil(numberOfPeople/10);

              var minPackageHotDogBun = Math.ceil(numberOfPeople/8);

console.log("The minimum number of packages of hot dogs required: " + minPackageHotDog);
          
console.log("The minimum number of packages of hot dog buns required: " + minPackageHotDogBun);

--

var minLeftOverHotDogs = (10 * minPackageHotDog - numberOfPeople);

var minLeftOverHotDogBuns = (8 * minLeftOverHotDogBun - numberOfPeople);

console.log('The number of hot dogs that will be left over: ' + minLeftOverHotDog);

console.log('The number of hot dog buns that will be left over: ' + minLeftOverHotDogBun);

/* Javascript program that calculates the number of packages of hot dogs
and the number of packages of hot dog buns needed for a cookout, with the minimum amount of leftovers*/

let readline = require('readline-sync'); // module for taking input

var main = () =>{
  
   //input of the number of people attending the cookout
   let num_people = parseInt(readline.question("Enter number of people attending the cookout? "));
  
   // variables to set the number of hotdogs per package and hotdog buns per package
   let hotdogs_per_package = 10;
   let hotdog_buns_per_package = 8;
  
   let hotdog_packages,hotdog_buns_packages;
  
// calculate hotdogs packages
   if(num_people%hotdogs_per_package == 0)
       hotdog_packages = parseInt(num_people/hotdogs_per_package);
   else
       hotdog_packages = parseInt(num_people/hotdogs_per_package)+1;
  
   // calculate hotdog buns packages
   if(num_people%hotdog_buns_per_package == 0)
       hotdog_buns_packages = parseInt(num_people/hotdog_buns_per_package);
   else
       hotdog_buns_packages = parseInt(num_people/hotdog_buns_per_package)+1;

   // calculate hotdogs leftovers
   let hotdog_leftover = (hotdog_packages*hotdogs_per_package) - num_people;
   // calculate hotdog buns leftovers
   let hotdog_buns_leftover = (hotdog_buns_packages*hotdog_buns_per_package) - num_people;
  
   // output
   console.log("The minimum number of packages of hot dogs required : "+hotdog_packages);
   console.log("The minimum number of packages of hot dog buns required : "+hotdog_buns_packages);
   console.log("The number of hot dogs that will be left over : "+hotdog_leftover);
   console.log("The number of hot dog buns that will be left over : "+hotdog_buns_leftover);
}

// call the main function
main()

//end of program

Output:
