Can anyone help me with this? Unable to display the output they asked for as the discount amount is different for different type

Question

A coffee shop manager is running a promotion and wants to offer a discount for coffee drinks.
The program you are given takes the discount value as input and defines a dictionary, where the names of the coffee drinks are set as keys, and their prices are set as values.
Write a program to discount all of the prices and output a new price list in the format shown below.

Sample Input
10

Sample Output
Americano: 45
Latte: 63
Flat White: 54
Espresso: 54
Cappuccino: 72
Mocha: 81
Hint : Use coffee.Keys.ToArray() inside the foreach loop.
Note the space after the ":" in the output.

My code :

using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
int discount = Convert.ToInt32(Console.ReadLine());

Dictionary<string, int> coffee = new Dictionary<string, int>();
coffee.Add("Americano", 50);
coffee.Add("Latte", 70);
coffee.Add("Flat White", 60);
coffee.Add("Espresso", 60);
coffee.Add("Cappuccino", 80);
coffee.Add("Mocha", 90);

foreach (string s in coffee.Keys.ToArray())

Console.WriteLine(s + ": " + Convert.ToInt32(coffee[s]-discount));

}
}
}

Answer 1

Mathe hint:
New price = list price - list price * discount / 100

Answer 2

JaScript Thanks a lot man.
I completely forgot that the discount is the percentage.
I thought that the input amount will be deducted from every value.
And so I was so confused when I saw the values they are asking for.

Again man,Thanks a lot.
