Question from the C# - Fundamentals test

What does the following code return:

static void Main(string[] args) { double ht=15.0;
double tva=20.0;
int nb_articles=4;
double total = ht + ht*(tva/100);
double totalnb=total*nb_articles;
Console.WriteLine("Le prix TTC d'un produit est = "+total); Console.WriteLine("Le prix TTC des "+nb_articles+" produits = "+totalnb); }
